A true VoD system has tremendous demand in the
market. The existing VoD system does not cater the needs
and demands of the market. The major problem in the VoD
system is serving of clients with expected QoS is difficult. In
this paper, we proposed a protocol and algorithm that
chains the proxy servers and subscribed clients. Our
objective is to send one server stream and this stream should
be served to N asynchronous clients. The server bandwidth
is scarcity and on the client uplink bandwidth is
underutilized. In this protocol, we are using client’s residual
bandwidth such that the load on the server bandwidth is
reduced. We have proved that optimal utilization of the
buffer and bandwidth for the entire VoD system and also
less rejection ratio of the clients.

As the various architectures and protocol have been implemented a true VoD system has great demand in the global users. The traditional VoD system does not provide the needs and demands of the global users. The major problem in the traditional VoD system is serving of video stream among clients is duplicated and streamed to the different clients, which consumes more server bandwidth and the client uplink bandwidth is not utilized and the performance of the system degrades. Our objective in this paper is to send one server stream sufficient to serve the many clients without duplicating the server stream. Hence we have proposed a protocol and algorithm that chains the proxy servers and subscribed clients utilize client’s uplink bandwidth such that the load on the server is reduced. We have also proved that less rejection ratio of the clients and better utilization of the buffer and bandwidth for the entire VoD system.

This document analyzes delays in unicast video streaming over IEEE 802.11 WLAN networks. It describes conducting an experiment using a testbed with a Darwin Streaming Server and WLAN probe to capture packets. The analysis found that video bitrate variations, packetization scheme, bandwidth load, and frame-based nature of video all impacted mean delay. Bursts of packets from video frames caused per-packet delay to increase in a sawtooth pattern. Increasing uplink load was also found to affect delay variations.
This paper proposes an adaptive energy management policy for wireless video streaming between a battery-powered client and server. It models the energy consumption of the server and client based on factors like CPU frequency, transmission power, and channel bandwidth. The paper formulates an optimization problem to assign optimal energy to each video frame. This maximizes system lifetime while meeting a minimum video quality requirement. Experimental results show the proposed policy increases overall system lifetime by 20% on average.

(Paper) MTcast: Robust and Efficient P2P-based Video Delivery for Heterogeneo...Naoki Shibata
In this paper, we propose a new video delivery method called MTcast (Multiple Transcode based video multicast) which achieves efficient simultaneous video delivery to multiple users with different quality requirements by relying on user nodes to transcode and forward video to other user nodes. In MTcast, each user specifies a quality requirement for a video consisting of bitrate, picture size and frame rate based on the user’s environmental resource limitation. All users can receive video with the specified quality (or near this quality) along a single delivery tree. The main characteristics of MTcast are in its scalability, high user satisfaction degree in received video quality, short startup latency and robustness against node failure. Through simulations, we have confirmed that MTcast can achieve much higher user satisfaction degree and robustness against node failure than the layered multicast method.

This paper proposes a new Hybrid Adaptive Mobile Streaming (HAMS) method for efficient video streaming on mobile devices using cloud services. HAMS uses Scalable Video Coding (SVC) to encode video files into base and enhancement layers. It first progressively downloads base layers, then adaptively streams enhancement layers to avoid video freezing while providing high video quality. An experiment compares HAMS to existing methods and finds HAMS achieves zero video freezes for up to three users, shorter freeze times, and better average video quality. The paper concludes HAMS is an effective method for mobile video streaming without freezing issues or reduced quality.

Video Streaming Compression for Wireless Multimedia Sensor NetworksIOSR Journals
This document discusses video streaming compression for wireless multimedia sensor networks. It proposes a cross-layer system that jointly controls the video encoding rate, transmission rate, and uses an adaptive parity scheme. At the application layer, video is compressed and divided into packets. These packets are encoded at the transport layer and forwarded through the network layer. An active buffer management scheme and adaptive parity check are used to maximize received video quality over lossy wireless links. Simulation results show the proposed techniques can achieve higher throughput by resequencing dropped packets. The goal is to design an efficient system for wireless transmission of compressed video that optimizes video quality.
This document analyzes the minimum delay bounds of chunk-based peer-to-peer video streaming systems. It finds that the uploading bandwidth of peers cannot be utilized to upload video chunks until the download of that chunk is complete, setting a limit on how fast chunks can disseminate. The document derives delay bounds for homogeneous and heterogeneous networks, and proposes a "snowball streaming" algorithm that approaches the minimum delay bound by prioritizing chunk dissemination to peers with the most bandwidth. Simulations show this algorithm achieves closer-to-optimal delays than static multi-tree streaming solutions.
The document describes a module on the transport layer from a course on computer networking principles, protocols, and practice. It covers basics of the transport layer, building reliable transport through connection establishment and data transmission, UDP as a simple connectionless protocol, and TCP as a reliable connected protocol. It discusses problems solved by the transport layer like multiplexing and reliability and how protocols 1-3 attempt to provide reliability under different assumptions.
The document discusses the network layer in computer networking. It covers two modes of operation for the network layer: datagram transmission mode and virtual circuit organization. In datagram mode, each packet contains source and destination addresses and routers make forwarding decisions on a hop-by-hop basis using routing tables. Virtual circuit organization pre-establishes paths between sources and destinations to simplify router forwarding.
The document discusses quality of service (QoS) in multimedia communication networks, including QoS parameters and classes, deterministic and predictive QoS parameters, guaranteed and best effort QoS, QoS-aware service models, scheduling and policing mechanisms like priority scheduling and weighted fair queueing, and QoS architectures like Integrated Services and Differentiated Services.

Quality of Experience and Quality of ServiceVideoguy
This document discusses quality of experience (QoE) and quality of service (QoS) for IP video conferencing. It explains that QoE is ensured by both application-based QoS (AQoS) and network-based QoS (NQoS). AQoS includes functions within the video conferencing application to enhance performance, like signaling protocols and media handling techniques. NQoS includes functions provided by the network, like scheduling and queuing. Both AQoS and NQoS work together to optimize the end-user experience of real-time video and audio transmission over IP networks.
Building Cloud-ready Video Transcoding System for Content Delivery Networks (...Zhenyun Zhuang
GLOBECOM 2012
Video streaming traffic of both VoD (Video on
Demand) and Live is exploding. Various types of businesses
and many people are relying on video streaming to attract
customers/users and for other purposes. Given the vast number
of video stream formats (e.g., MP4, FLV) and transmission
protocols (e.g., HTTP, RTMP, RTSP) for supporting varying
types of playback terminals (particularly mobile devices such as
iphone/ipad and Android phones), video content providers often
need to transcode videos to multiple formats in order to stream
to different types of users.
Being time-sensitive and requiring high bandwidth, video
streaming exerts high pressure on underlying delivery networks.
Content Delivery Network (CDN) providers can help their
customers quickly and reliably distribute stream contents to end
users. In addition to distributing video streams, CDN providers
typically allow their customers to perform video transcoding on
CDN platforms. With the high volume of video streams and the
bursty transcoding workload, CDN providers are eager to deploy
elastic and optimized cloud-based transcoding platforms.

Colored Image Watermarking Technique Based on HVS using HSV Color ModelIDES Editor
The Human Visual System is found to be less
sensitive to the highly textured area of the image. Moreover,
in all colours the blue is least sensitive to the HVS (Human
Visual System). While working on colored images when using
the mathematical and biological models of HVS, the preferred
colour model must be HSV (Hue, Saturation and Value) colour
model rather than RGB colour model because it most closely
defines how the image is interpreted by HVS. The high visual
transparency in the technique is achieved by making use of
highly textured block in luminance channel for watermark
insertion. Moreover, the choice of selecting appropriate area
for watermark insertion is also influenced by making use of
‘Hue’ property of the image in the chrominance channel to
enhance the visual transparency even more. Watermark is
made highly robust against different types of attacks by
performing the watermark insertion in transformed domain
and making use of the transformation functions such as DWT,
DCT and SVD. The results demonstrated the robustness of
the technique against various types of attacks and comparison
through aforesaid results the technique is proven to be more
robust against previous techniques making use of HSI colour
model.

A Runtime Evaluation Methodology and Framework for Autonomic SystemsIDES Editor
An autonomic system provides self-adaptive ability
that enables system to dynamically adjust its behavior on
environmental changes or system failure. Fundamental
process of adaptive behavior in an autonomic system is consist
of monitoring system or/and environment information,
analyzing monitored information, planning adaptation policy
and executing selected policy. Evaluating system utility is
one of a significant part among them. We propose a novel
approach on evaluating autonomic system at runtime. Our
proposed method takes advantage of a goal model that has
been widely used at requirement elicitation phase to capture
system requirements. We suggest the state-based goal model
that is dynamically activated as the system state changes. In
addition, we defined type of constraints that can be used to
evaluate goal satisfaction level. We implemented a prototype
of autonomic computing software engine to verity our proposed
method. We simulated the behavior of the autonomic
computing engine with the home surveillance robot scenario
and observed the validity of our proposed method

This document proposes an improved spread spectrum watermarking technique to withstand geometric deformations. The technique uses Direct Sequence Code Division Multiple Access (DS-CDMA) and embeds the watermark by modulating a pseudo-random noise sequence. It normalizes the cover image before embedding to achieve robustness against geometric attacks like rotation and scaling. The watermark is extracted using correlation between the watermarked image and pseudo-random noise sequence. Experimental results show the technique achieves a low bit error rate under various geometric attacks when the watermark strength is increased.

Nonlinear dynamics of a third order phase locked
loop (PLL) using a resonant low pass filter in the face of
continuous wave (CW) and frequency modulated (FM) input
signals is examined. The role of design parameters of the
loop resonant filter and the modulation index of the input FM
signal on the system dynamics is studied numerically as well
as experimentally. The occurrence of chaotic oscillations in
the PLL is verified by evaluating some well-known chaos
quantifiers like Lyapunov Exponents from the numerical time
series data.
Coordinated Multi-Agents Based Patient Scheduling Using Genetic AlgorithmIDES Editor
Scheduling is inevitable and an integral part of
hospital management. Effective patient scheduling can
improve hospital service quality by minimizing the
waiting/stay time for patients in the hospital and operation
efficiency by optimizing the utilization of resources. However,
in practice, the schedulers usually take substantial amount of
time to do the scheduling manually and also by using various
traditional scheduling algorithms. Motivated by the real needs
in hospital environments this paper focuses on finding an
optimal schedule using search based optimization techniques
like Genetic Algorithm (GA) and multi-Agents. Agents have
been proved to be an effective approach to resource allocation
because of its coordination and social abilities. Exact methods
such as branch and bound method, and dynamic
programming take considerable computing time and
hardware requirements in this application domain.
Considering the crucial time in the hospital environments,
combinatorial search space algorithms (like GA) with
precedence constraints have been selected to find a good
solution with the following objectives: Customer satisfaction
and Operational Efficiency. Customer satisfaction is achieved
by minimizing the waiting time for patients and operational
efficiency by minimizing the idle time of the resource.
Detecting Original Image Using Histogram, DFT and SVMIDES Editor
Information hiding for covert communication is rapidly
gaining momentum. With sophisticated techniques being
developed in steganography, steganalysis needs to be
universal. In this paper we propose Universal Steganalysis
using Histogram, Discrete Fourier Transform and SVM
(SHDFT). The stego image has irregular statistical
characteristics as compare to cover image. Using Histogram
and DFT, the statistical features are generated to train One-
Class SVM to discriminate the cover and stego image.
SHDFT algorithm is found to be efficient and fast since the
number of statistical features is less compared to the
existing algorithm.
Near-Far Resistance of MC-DS-CDMA Communication SystemsIDES Editor
In this paper, the near-far resistance of the minimum

MC-DS-CDMA has better performance on near-far resistance
than that of DS-CDMA.
Face Recognition Using Sign Only CorrelationIDES Editor
In this work we examine a face recognition system
based on advanced correlation filters. A thorough
theoretical design analysis of, Minimum Average
Correlation Energy (MACE) filters and Optimum Trade-off
Synthetic Discriminant Function (OTSDF) also commonly
known as Optimal Trade-off Filter (OTF) is provided. In
practice one of the major computational aspects in the
correlation filter design is representation of complex
floating point Discrete Fourier Transform (DFT)
coefficients using limited precision memory. In order to over
come the floating point memory requirement of the
correlation based filters for systems with limited
computational resources use of Discrete Cosine Transform
Sign-Only Correlation (DCTSOC) which deals with only the
sign information of the Discrete Cosine Transform (DCT)
has been proposed. The proposed method is tested for
synthesis of OTF and a comparison of recognition rate for
frontal face identification is made between OTF using
DSOC (OTDS) and standard OTF
New Signature Derivation using Existing SignaturesIDES Editor
In banks, as part of normal procedure, receipts
for deposits, statements of the bank account or credit card
account are regularly issued to customers. This whole
procedure is time consuming. Also, officials often find it
difficult to sign for all the documents required by a
customer though the related sub-processes are completed
and corresponding documents are digitally signed. We
consider the scenario of e-receipt generation during echeque
processing, where the subprocess like e-cheque
verification and receiving acknowledgement from cheque
clearing bank are completed and digitally signed. But there
is need for e-receipt to be generated by the bank for the
customer. When the number of e-cheques increase, it is a
burden for the bank to issue e-receipts. In this scenarios, we
observe that, it would be interesting if customers themselves
are capable of generating signed receipts based on the
signatures available on already completed transactions. This
calls for signature of a document to be derived from existing
signatures of related documents. By this a customer can
derive signatures on his own without the intervention of the
bank which inturn reduces the work load on the bank. In all
the signature derivations we make, we take care that a new
signature derived is similar to the one that the signer would
have generated if he had signed himself and also all
signatures either existing or derived are verified using the
same verification equation.
The main problem is to avoid the complexity of retrieving the video content without streaming problem in multi network clients. The proposed work is to improve Collaboration among streaming contents on server resources in order to improve the network performance. Implementing network collaboration on a content delivery scenario, with a strong reduction of data transferred via servers. Audio and video files are transmitted in blocks to clients through the peer using the Network Coding Equivalent Content Distribution scheme. The objective of the system is to tolerate out-of-order arrival of blocks in the stream and is resilient to transmission losses of an arbitrary number of intermediate blocks, without affecting the verifiability of remaining blocks in the stream. To formulate the joint rate control and packet scheduling problem as an integer program where the objective is to minimize a cost function of the expected video distortion. Suggestions of cost functions are proposed in order to provide service differentiation and address fairness among users.
This document summarizes a study on simulating video streaming in multi-hop networks. It discusses using multiple access networks to stream video from a server to clients to aggregate bandwidth. The study formulates the problem of optimizing video streaming over internet packet traces as an integer program to minimize distortion. It proposes authenticating initial video streams using signatures and fragmenting/encoding content into blocks stored across peers to improve security and efficiency of content distribution in the presence of packet loss. Simulation results show this approach can reduce downloading time and avoid data loss during multi-hop video streaming.
Live multimedia streaming and video on demand issues and challengeseSAT Journals
Live streaming and video on demand face challenges in providing quality service over the internet. The key issues are quality of service due to network instability and degraded performance when serving large numbers of users. While peer-to-peer architectures can help solve issues of limited server resources, they introduce challenges such as ensuring sufficient upload bandwidth from peers and maintaining stable connectivity. Additional issues include firewalls and internet service provider throttling impacting streaming quality, and challenges in peer discovery and storage overhead in peer-to-peer video on demand systems. Addressing these architectural and performance issues is important for providing the best experience of streaming and video on demand services.

The document proposes a new mobile video streaming framework called AMES-Cloud that leverages cloud computing. It has two parts: Adaptive Mobile Video Streaming (AMoV) and Efficient Communal Video Sharing (ESoV). AMoV allows each user's private agent to adaptively adjust their streaming flow based on link quality feedback. ESoV monitors social networks between users, and their agents prefetch video content. The framework aims to provide high quality mobile video streaming services by adapting to varying network conditions and enabling social video sharing through cloud resources.
A NOVEL ADAPTIVE CACHING MECHANISM FOR VIDEO ON DEMAND SYSTEM OVER WIRELESS M...IJCNCJournal
Video on Demand (VOD) system over the wireless mobile network is a system that provides video services to mobile clients. The main problem with these systems is the high service delay where the mobile clients have to wait to view their favorite movie. The importance of this paper is based on finding a solution on how to reduce the delay time in the VOD system. This paper introduces a novel caching mechanism named
Proxy Server Cache mechanism to tackle the issue of service delay. This delay happens when the broadcasting phase that is related to the first segment is missed by a client from the current broadcasting channels. In this mechanism, the video’s first segment is stored on a server of a stationary proxy type. The
delayed clients will directly acquire the first segment from the proxy server instead of waiting for the following broadcasting channel pertaining to the first segment. The proposed scheme ensuresobtaining the first segment from mobile clients when they arrive. Additionally, the performance of the proposed scheme is validated by applying the VOD system, which can involve the balancing mechanism to retain particular requests through to the local proxy server to provide a fair dissemination for these requests. The obtained result confirms that the proposed scheme reduces the time delay of the system in comparison with the best existing schemes. The results of the average time delay in the Proxy-Cache scheme is 179.2505
milliseconds when 10 clients arrive each minute (Client/minute), the average time delay is 140 milliseconds when the video lengths are 30, 60 and 90. Meanwhile, the failure probability for obtaining the first segment of the video remains zero when the number of arrived requests is set to2, 4, 6, 8 and 10.
PEER-TO-PEER INTERACTIVE VOD STREAMING USING NCECDJayanthGubbi
This document presents a proposed system for video-on-demand streaming using a peer-to-peer network with network coding. The existing systems have issues like long buffering times and high server loads. The proposed system divides videos into segments that are distributed across peer nodes. It uses network coding to encode the segments, which helps decrease server stress and loading times. The key modules are an admin that processes client requests and sends videos, and clients that make requests and receive videos based on their bandwidth. The goal of this approach is to provide efficient video streaming with interactive controls and load balancing.
A FRAMEWORK FOR MOBILE VIDEO STREAMING AND VIDEO SHARING IN CLOUDJournal For Research
The transmission of data has grown over years in all the streams of technology. Video and image data plays a very important position in communication around the globe. The usage of Medias over mobile devices had exploded years ago in technology. However, the usage of traditional network connecting protocols and the service providers are providing lack of quality in services. As the number of users who uses mobile phones is increasing day by day the video traffic over network is also increasing thereby causes disruption in the service which is caused by low bandwidth. Due to this disruption the wireless cannot able to satisfy the users demand for video streaming which eventually causes long buffering time. Influencing cloud computing knowledge to gain advantage over this issue we suggest two solutions. i) Mobile Video Streaming (MoV) and Social Video Sharing (SoV). MoV will create a private cloud for each mobile user which adjusts the bit rate based on return value using scalable video coding technique to improve the scalability and efficient utilization of bandwidth. SoV uses the agent to pre fetch the video data for effective sharing and to reduce the buffering time.
Reliable content video streaming services for p2 p networksJayanthGubbi
This document presents a proposed system for reliable content video streaming services for peer-to-peer (P2P) networks using Network Coding Equivalent Content Distribution (NCECD). The existing systems have drawbacks like more buffering time, time spent optimizing large file distribution, and long wait times for videos to load. The proposed system aims to provide interactive video-on-demand services in P2P networks with reduced delay, scalability, flexibility and low latency. It divides videos into segments stored across peer local storage in a distributed manner, allowing clients to pick servers without additional search. This supports dynamic peer networks while solving server load balancing and reducing loading/buffering times.
An Overview on Multimedia Transcoding Techniques on Streaming Digital Contentsidescitation
The current IT infrastructure as well as various
commercial applications are directly formulated based on
deployment in multimedia system e.g. education, marketing,
risk management, tele-medicines, military etc. One of the
challenges found in using such application is to deliver
uninterrupted stream of video between multiple terminals
e.g. smart-phone, PDAs, laptops, IPTV etc. The research shows
that there is a stipulated need of designing novel mechanism
of bit rate adjustment as well as format conversion policy so
that the source stream may stream well in diverse end devices
with multiple configuration of processor, memory, decoding
etc. This paper discusses various eminent points from
literature that will throw better highlights in understanding
a schema of direct digital-to-digital data conversion of one
encoding to another termed as transcoding. Although
multimedia transcoding has covered more than a decade in
the area of research, but unfortunately, there is a huge trade-
off between the application, service, resource constraint, and
hardware design that gives rise to QoS issues.
This document proposes a new retrieval strategy called CoRe for peer-to-peer video-on-demand systems. CoRe aims to minimize response time and maximize throughput. It does this by selecting multiple serving peers to collaboratively service each request based on factors like distance and available resources. The document outlines limitations of existing strategies, describes the CoRe algorithm in detail, and presents experimental results showing CoRe performs better than the Least Load First algorithm, especially under heavy workloads.
The impact of jitter on the HEVC video streaming with Multiple CodingHakimSahour
This document discusses the impact of jitter on video quality when streaming HEVC encoded video over wireless networks. It presents a study evaluating the effects of quantization parameter (QP) values, video content, and jitter on quality of experience (QoE). The study finds that using higher QP values, which lowers bitrate and increases compression, degrades video quality as measured by PSNR. It also finds that different video content results in varying PSNR values for the same encoding settings. Additionally, the results show that adjusting the QP value can help recover from the negative effects of jitter on received video quality. The document proposes using multiple description coding (MDC) to further improve transmission over error-prone wireless channels.
This document proposes a distributed video-on-demand (DVoD) system using a grid-based architecture. The key components are a media splitter, scheduler, and streaming servers distributed across grid nodes. The media is split into parts and distributed to nodes for storage. When a client requests a video, the scheduler coordinates streaming the split parts from multiple nodes to the client. This distributed approach aims to address issues like load balancing, scalability, and fault tolerance in a cost-effective manner compared to centralized systems. Related work on distributed streaming, peer-to-peer architectures, and adaptive encoding is also discussed.
Efficient and thorough data collection and its timely analysis are critical for disaster response and recovery in order to save people's lives during disasters. However, access to comprehensive data in disaster areas and their quick analysis to transform the data to actionable knowledge are challenging. With the popularity and pervasiveness of mobile devices, crowdsourcing data collection and analysis has emerged as an effective and scalable solution. This paper addresses the problem of crowdsourcing mobile videos for disasters by identifying two unique challenges of 1) prioritizing visual data collection and transmission under bandwidth scarcity caused by damaged communication networks and 2) analyzing the acquired data in a timely manner. We introduce a new crowdsourcing framework for acquiring and analyzing the mobile videos utilizing fine granularity spatial metadata of videos for a rapidly changing disaster situation. We also develop an analytical model to quantify the visual awareness of a video based on its metadata and propose the visual awareness maximization problem for acquiring the most relevant data under bandwidth constraints. The collected videos are evenly distributed to off-site analysts to collectively minimize crowdsourcing efforts for analysis. Our simulation results demonstrate the effectiveness and feasibility of the proposed framework.
1. The document describes a hierarchical framework for allocating network resources for robust home video streaming.
2. Key aspects of the framework include using TCP for transport, scalable video coding with temporal and SNR layers to adapt to bandwidth fluctuations, and prioritizing frame types to minimize quality impacts when frames must be dropped.
3. The framework aims to provide a recognizable video stream even during periods of network overload by gracefully degrading quality instead of causing stalls or failures.
Analyzing Video Streaming Quality by Using Various Error Correction Methods o...IJERA Editor
Transmission video over ad hoc networks has become one of the most important and interesting subjects of study for researchers and programmers because of the strong relationship between video applications and frequent users of various mobile devices, such as laptops, PDAs, and mobile phones in all aspects of life. However, many challenges, such as packet loss, congestion (i.e., impairments at the network layer), multipath fading (i.e., impairments at the physical layer) [1], and link failure, exist in transferring video over ad hoc networks; these challenges negatively affect the quality of the perceived video [2].This study has investigated video transfer over ad hoc networks. The main challenges of transferring video over ad hoc networks as well as types of errors that may occur during video transmission, various types of video mechanisms, error correction methods, and different Quality of Service (QoS) parameters that affect the quality of the received video are also investigated.
Delay Efficient Method for Delivering IPTV ServicesIJERA Editor
Internet Protocol Television (IPTV) is a system through which Internet television services are delivered using
the architecture and networking methods of the Internet Protocol Suite over a packet-switched network
infrastructure, e.g., the Internet and broadband Internet access networks, instead of being delivered through
traditional radio frequency broadcast, satellite signal, and cable television (CATV) formats. IPTV provides
mainly three services: live TV, catch up TV, and video on demand (VoD).This paper focuses on delivering the
live TV services by exploiting the virtualised cloud architecture of the IPTV and statistical multiplexing. The
VoD tasks are prescheduled so that there will be less Instant Channel Change (ICC) delay. We select a proper
scheduling algorithm for rescheduling the VoD tasks. We then implement the scheduling algorithm for preshifting
the VoD tasks.
ADVANCES IN CHANNEL-ADAPTIVE VIDEO STREAMINGVideoguy
This document summarizes recent advances in channel-adaptive video streaming. It reviews adaptive media playout at the client to reduce latency, rate-distortion optimized packet scheduling to determine the best packet to send, and channel-adaptive packet dependency control to improve error robustness and reduce latency. It also discusses challenges for wireless video streaming and different wireless streaming architectures.
The document discusses distributed multimedia systems (DMMS). It defines DMMS as consisting of multimedia databases, proxy servers, information servers, and clients intended for distributing multimedia content over networks. Key requirements for DMMS include supporting continuous media like audio and video through continuous data transfers with high bandwidth, as well as sophisticated quality of service management to ensure service requests are met. The basic architecture of DMMS includes databases, proxy/information servers, clients, and wired or wireless networks to deliver multimedia streams while meeting timing requirements like quality of service.
Optimizing cloud resources for delivering iptv services through virtualizationJPINFOTECH JAYAPRAKASH
The document discusses optimizing cloud resources for delivering IPTV services through virtualization. It proposes using a cloud computing infrastructure with virtualization to flexibly handle the combined workload of multiple services like live TV and video-on-demand. The system would intelligently time-shift selected services to take advantage of different deadlines and effectively multiplex the services. An optimization formulation is constructed to compute resource needs to support multiple services without missing any deadlines. Results from a simulator using real IPTV network traces show the approach can significantly reduce server load compared to existing systems.

Power System State Estimation - A ReviewIDES Editor
This document provides a review of power system state estimation techniques. It discusses both static and dynamic state estimation algorithms. For static state estimation, it covers weighted least squares, decoupled, and robust estimation methods. Weighted least squares is commonly used but can have numerical instability issues. Decoupled state estimation approximates the gain matrix for faster computation. Robust estimation uses M-estimators and other techniques to handle outliers and bad data. Dynamic state estimation applies Kalman filtering, leapfrog algorithms, and other methods to continuously monitor system states over time.
Artificial Intelligence Technique based Reactive Power Planning Incorporating...IDES Editor
This document summarizes a research paper that proposes using artificial intelligence techniques and FACTS controllers for reactive power planning in real-time power transmission systems. The paper formulates the reactive power planning problem and incorporates flexible AC transmission system (FACTS) devices like static VAR compensators (SVC), thyristor controlled series capacitors (TCSC), and unified power flow controllers (UPFC). Evolutionary algorithms like evolutionary programming (EP) and differential evolution (DE) are applied to find the optimal locations and settings of the FACTS controllers to minimize losses and costs. Simulation results on IEEE 30-bus and 72-bus Indian test systems show that UPFC performs best in reducing losses compared to SVC and TCSC.

Damping of power system oscillations with the help

(SVC)-based controllers are thoroughly investigated in this
paper. This study presents robust tuning of PID-PSS and
SVC-based controllers using Genetic Algorithms (GA) in
multi machine power systems by considering detailed model
of the generators (model 1.1). The effectiveness of FACTSbased
controllers in general and SVC-based controller in
particular depends upon their proper location. Modal
controllability and observability are used to locate SVC–based
controller. The performance of the proposed controllers is
compared with conventional lead-lag power system stabilizer

performance.
Optimal Placement of DG for Loss Reduction and Voltage Sag Mitigation in Radi...IDES Editor
This paper presents the need to operate the power
system economically and with optimum levels of voltages has
further led to an increase in interest in Distributed
Generation. In order to reduce the power losses and to improve
the voltage in the distribution system, distributed generators
(DGs) are connected to load bus. To reduce the total power
losses in the system, the most important process is to identify
the proper location for fixing and sizing of DGs. It presents a
new methodology using a new population based meta heuristic
approach namely Artificial Bee Colony algorithm(ABC) for
the placement of Distributed Generators(DG) in the radial
distribution systems to reduce the real power losses and to
improve the voltage profile, voltage sag mitigation. The power
loss reduction is important factor for utility companies because
it is directly proportional to the company benefits in a
competitive electricity market, while reaching the better power
quality standards is too important as it has vital effect on
customer orientation. In this paper an ABC algorithm is
developed to gain these goals all together. In order to evaluate
sag mitigation capability of the proposed algorithm, voltage
in voltage sensitive buses is investigated. An existing 20KV
network has been chosen as test network and results are
compared with the proposed method in the radial distribution
system.
Line Losses in the 14-Bus Power System Network using UPFCIDES Editor
Controlling power flow in modern power systems
can be made more flexible by the use of recent developments
in power electronic and computing control technology. The
Unified Power Flow Controller (UPFC) is a Flexible AC
transmission system (FACTS) device that can control all the
three system variables namely line reactance, magnitude and
phase angle difference of voltage across the line. The UPFC
provides a promising means to control power flow in modern
power systems. Essentially the performance depends on proper
control setting achievable through a power flow analysis
program. This paper presents a reliable method to meet the
requirements by developing a Newton-Raphson based load
flow calculation through which control settings of UPFC can
be determined for the pre-specified power flow between the
lines. The proposed method keeps Newton-Raphson Load Flow
(NRLF) algorithm intact and needs (little modification in the
Jacobian matrix). A MATLAB program has been developed to
calculate the control settings of UPFC and the power flow
between the lines after the load flow is converged. Case studies
have been performed on IEEE 5-bus system and 14-bus system
to show that the proposed method is effective. These studies
indicate that the method maintains the basic NRLF properties
such as fast computational speed, high degree of accuracy and
good convergence rate.
Study of Structural Behaviour of Gravity Dam with Various Features of Gallery...IDES Editor
The size and shape of opening in dam causes the
stress concentration, it also causes the stress variation in the
rest of the dam cross section. The gravity method of the analysis
does not consider the size of opening and the elastic property
of dam material. Thus the objective of study is comprises of
the Finite Element Method which considers the size of
opening, elastic property of material, and stress distribution
because of geometric discontinuity in cross section of dam.
Stress concentration inside the dam increases with the opening
in dam which results in the failure of dam. Hence it is
necessary to analyses large opening inside the dam. By making
the percentage area of opening constant and varying size and
shape of opening the analysis is carried out. For this purpose
a section of Koyna Dam is considered. Dam is defined as a
plane strain element in FEM, based on geometry and loading
condition. Thus this available information specified our path
of approach to carry out 2D plane strain analysis. The results
obtained are then compared mutually to get most efficient
way of providing large opening in the gravity dam.
Assessing Uncertainty of Pushover Analysis to Geometric ModelingIDES Editor
Pushover Analysis a popular tool for seismic
performance evaluation of existing and new structures and is
nonlinear Static procedure where in monotonically increasing
loads are applied to the structure till the structure is unable
to resist the further load .During the analysis, whatever the
strength of concrete and steel is adopted for analysis of
structure may not be the same when real structure is
constructed and the pushover analysis results are very sensitive
to material model adopted, geometric model adopted, location
of plastic hinges and in general to procedure followed by the
analyzer. In this paper attempt has been made to assess
uncertainty in pushover analysis results by considering user
defined hinges and frame modeled as bare frame and frame
with slab modeled as rigid diaphragm and results compared
with experimental observations. Uncertain parameters
considered includes the strength of concrete, strength of steel
and cover to the reinforcement which are randomly generated
and incorporated into the analysis. The results are then
compared with experimental observations.

Selfish Node Isolation & Incentivation using Progressive ThresholdsIDES Editor
The problems associated with selfish nodes in
MANET are addressed by a collaborative watchdog approach
which reduces the detection time for selfish nodes thereby
improves the performance and accuracy of watchdogs[1]. In
the related works they make use of credit based systems, reputation
based mechanisms, pathrater and watchdog mechanism
to detect such selfish nodes. In this paper we follow an approach
of collaborative watchdog which reduces the detection
time for selfish nodes and also involves the removal of such
selfish nodes based on some progressively assessed thresholds.
The threshold gives the nodes a chance to stop misbehaving
before it is permanently deleted from the network.
The node passes through several isolation processes before it
is permanently removed. Another version of AODV protocol
is used here which allows the simulation of selfish nodes in
NS2 by adding or modifying log files in the protocol.
Various OSI Layer Attacks and Countermeasure to Enhance the Performance of WS...IDES Editor
Wireless sensor networks are networks having non
wired infrastructure and dynamic topology. In OSI model each
layer is prone to various attacks, which halts the performance
of a network .In this paper several attacks on four layers of
OSI model are discussed and security mechanism is described
to prevent attack in network layer i.e wormhole attack. In
Wormhole attack two or more malicious nodes makes a covert
channel which attracts the traffic towards itself by depicting a
low latency link and then start dropping and replaying packets
in the multi-path route. This paper proposes promiscuous mode
method to detect and isolate the malicious node during
wormhole attack by using Ad-hoc on demand distance vector
routing protocol (AODV) with omnidirectional antenna. The
methodology implemented notifies that the nodes which are
not participating in multi-path routing generates an alarm
message during delay and then detects and isolate the
malicious node from network. We also notice that not only
the same kind of attacks but also the same kind of
countermeasures can appear in multiple layer. For example,
misbehavior detection techniques can be applied to almost all
the layers we discussed.

The recent advancements in the wireless technology
and their wide-spread deployment have made remarkable
enhancements in efficiency in the corporate and industrial

wireless technology is creating a need for more secure wireless
Ad hoc networks. This paper aims researched and developed
a new protocol that prevents wormhole attacks on a ad hoc

no GPS dependencies.
Cloud Security and Data Integrity with Client Accountability FrameworkIDES Editor
This document summarizes a proposed cloud security and data integrity framework that provides client accountability. The framework aims to address issues like lack of user control over cloud data, need for data transparency and tracking, and ensuring data integrity. It proposes using JAR (Java Archive) files for data sharing due to benefits like portability. The framework incorporates client-side verification using MD5 hashing, digital signature-based authentication of JAR files, and use of HMAC to ensure data integrity. It also uses password-based encryption of log files to keep them tamper-proof. The framework is intended to provide both accountability and security for data sharing in cloud environments.
Genetic Algorithm based Layered Detection and Defense of HTTP BotnetIDES Editor
A System state in HTTP botnet uses HTTP protocol
for the creation of chain of Botnets thereby compromising
other systems. By using HTTP protocol and port number 80,
attacks can not only be hidden but also pass through the
firewall without being detected. The DPR based detection
leads to better analysis of botnet attacks [3]. However, it
provides only probabilistic detection of the attacker and also
time consuming and error prone. This paper proposes a Genetic
algorithm based layered approach for detecting as well as
preventing botnet attacks. The paper reviews p2p firewall
implementation which forms the basis of filtering.
Performance evaluation is done based on precision, F-value
and probability. Layered approach reduces the computation
and overall time requirement [7]. Genetic algorithm promises
a low false positive rate.
Enhancing Data Storage Security in Cloud Computing Through SteganographyIDES Editor
This document summarizes a research paper that proposes a method for enhancing data security in cloud computing through steganography. The method hides user data in digital images stored on cloud servers. When data needs to be accessed, it is extracted from the images. The document outlines the cloud architecture and security issues addressed. It then describes the proposed system architecture, security model, and data storage and retrieval process. Data is partitioned and hidden in multiple images to improve security. The goal is to prevent unauthorized access to user data stored on cloud servers.
The main tasks of a Wireless Sensor Network
(WSN) are data collection from its nodes and communication
of this data to the base station (BS). The protocols used for
communication among the WSN nodes and between the WSN
and the BS, must consider the resource constraints of nodes,
battery energy, computational capabilities and memory. The
WSN applications involve unattended operation of the network
over an extended period of time. In order to extend the lifetime
of a WSN, efficient routing protocols need to be adopted. The
proposed low power routing protocol based on tree-based
network structure reliably forwards the measured data towards
the BS using TDMA. An energy consumption analysis of the
WSN making use of this protocol is also carried out. It is
found that the network is energy efficient with an average
duty cycle of 0:7% for the WSN nodes. The OmNET++
simulation platform along with MiXiM framework is made
use of.
Permutation of Pixels within the Shares of Visual Cryptography using KBRP for...IDES Editor
The security of authentication of internet based
co-banking services should not be susceptible to high risks.
The passwords are highly vulnerable to virus attacks due to
the lack of high end embedding of security methods. In order
for the passwords to be more secure, people are generally
compelled to select jumbled up character based passwords
which are not only less memorable but are also equally prone
to insecurity. Multiple use of distributed shares has been
studied to solve the problem of authentication by algorithms
based on thresholding of pixels in image processing and visual
cryptography concepts where the subset of shares is considered
for the recovery of the original image for authentication using
correlation function[1][2].The main disadvantage in the above
study is the plain storage of shares and also one of the shares
is being supplied to the customer, which will lead to the
possibility of misuse by a third party. This paper proposes a
technique for scrambling of pixels by key based random
permutation (KBRP) within the shares before the
authentication has been attempted. Total number of shares to
be created is dependent on the multiplicity of ownership of
the account. By this method the problem of uncertainty among
the customers with regard to security, storage, retrieval of
holding of half of the shares is minimized.
This paper presents a trifocal Rotman Lens Design
approach. The effects of focal ratio and element spacing on
the performance of Rotman Lens are described. A three beam
prototype feeding 4 element antenna array working in L-band
has been simulated using RLD v1.7 software. Simulated
results show that the simulated lens has a return loss of –
12.4dB at 1.8GHz. Beam to array port phase error variation
with change in the focal ratio and element spacing has also
been investigated.
Band Clustering for the Lossless Compression of AVIRIS Hyperspectral ImagesIDES Editor
Hyperspectral images can be efficiently compressed
through a linear predictive model, as for example the one
used in the SLSQ algorithm. In this paper we exploit this
predictive model on the AVIRIS images by individuating,
through an off-line approach, a common subset of bands, which
are not spectrally related with any other bands. These bands
are not useful as prediction reference for the SLSQ 3-D
predictive model and we need to encode them via other
prediction strategies which consider only spatial correlation.
We have obtained this subset by clustering the AVIRIS bands
via the clustering by compression approach. The main result
of this paper is the list of the bands, not related with the
others, for AVIRIS images. The clustering trees obtained for
AVIRIS and the relationship among bands they depict is also
an interesting starting point for future research.

Texture Unit based Monocular Real-world Scene Classification using SOM and KN...IDES Editor
In this paper a method is proposed to discriminate
real world scenes in to natural and manmade scenes of similar
depth. Global-roughness of a scene image varies as a function
of image-depth. Increase in image depth leads to increase in
roughness in manmade scenes; on the contrary natural scenes
exhibit smooth behavior at higher image depth. This particular
arrangement of pixels in scene structure can be well explained
by local texture information in a pixel and its neighborhood.
Our proposed method analyses local texture information of a
scene image using texture unit matrix. For final classification
we have used both supervised and unsupervised learning using
K-Nearest Neighbor classifier (KNN) and Self Organizing
Map (SOM) respectively. This technique is useful for online
classification due to very less computational complexity.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Taking AI to the Next Level in Manufacturing.pdfssuserfac0301
Read Taking AI to the Next Level in Manufacturing to gain insights on AI adoption in the manufacturing industry, such as:
1. How quickly AI is being implemented in manufacturing.
2. Which barriers stand in the way of AI adoption.
3. How data quality and governance form the backbone of AI.
4. Organizational processes and structures that may inhibit effective AI adoption.
6. Ideas and approaches to help build your organization's AI strategy.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
