Abstract: The computer networks have evolved themselves into an altogether new generation with Mobile Ad-
Hoc networks. The Mobile Ad-Hoc Networks are increasingly becoming more sophisticated and complex in
terms of topology, routing and security[1][2][3]The new age MANETs incorporate routing of heavier traffic
classes like audio, video and multimedia. It has become important to study the performance characteristics of
the multimedia traffic class in MANETS [10] that includes packet loss rate and throughput. In this paper we will
discuss these performance parameter throughput under different scenarios like varying Bandwidth, channel
error rate, delay and fragment size.
Keywords: MANET, Packet loss rate, Throughput, Bandwidth, Fragment size
I. Introduction
In this paper we present a relatively complex network with both UDP and TCP traffic flowing in the
network. If we study the performance of UDP traffic class in a network, it becomes easier to predict the
behaviour of multimedia traffic class as it will be sent over the UDP in the simulations[9]
We analyse the UDP traffic on the main router to router link for the following parameters.
Throughput: Throughput or network throughput is number of bits delivered successfully per second to the
destination. It is the sum of bits received successfully by all destinations.This data may be delivered over a
physical or logical link. The throughput is measured in bits per second (bps).
Mathematically, it can be defined as:
Throughput= N/1000
Where N is the number of bits which is received successfully by all destinations [4]
II. Methodology
The primary traffic class that multimedia adopts is UDP. IN multimedia communication for MPEG-4
traffic, if we analyse the characteristics of UDP traffic for throughput and other network performance
parameters then we can predict the behaviour of MPEG-4 also in a network with multi-class traffic. For this
purpose a n/w generating both TCP and UDP traffic classes is created and tested.
The topology of the network created is as follows:](https://image.slidesharecdn.com/e0712830-150319050909-conversion-gate01/85/Analysis-of-Multimedia-Traffic-Performance-in-a-Multi-Class-traffic-environment-for-UDP-traffic-class-1-320.jpg)

The network has 2 source nodes (S1 and S2), one generating TCP traffic and the other generating UDP
traffic to be transferred at the destination node (d) [7][8] The network parameters are changed on the link (r1-r2)
as shown in the figure.
The following parameters are changed in the network. In first case, the bandwidth of the main router
to router link (r1-r2) is changed keeping the other network parameters unchanged. In the second scenario the
delay of the main router to router link (r1-r2) is changed keeping the other network parameters unchanged. In
the third scenario the error rate of the main link is changed and in the fourth scenario the packet size is
changed.
The result that we present is the effect of fragment size on THROUGHPUT. We have kept the delay to
be constant and analysed with varying bandwidths and error rate.
We observed the throughput for different fragment sizes at 10 ms, 50ms and 100ms delay

Selective Green Device Discovery for Device to Device Communication
The D2D communication is expected to improve devices’ energy-efficiency, which has become a
major requirement of the future wireless network. Before the D2D communication can be performed, the
device discovery between devices must be done. The previous works usually only assumed one mode of
device discovery, i.e. either use network-assisted (with network supervision) or independent (without
network supervision) device. Therefore, we propose a selective device discovery for device-to-device
(D2D) communication that can utilize both device discovery modes and maintain devices’ energyefficiency.
Different from previous works, our proposed method selects the best device discovery mode to
get the best energy-efficiency. Moreover, to further improve the energy-efficiency, our proposed method
also deployed in D2D cluster with multiple cluster heads. The proposed method selects the most suitable
mode using thresholds (cluster energy consumption and new device acceptance) and cluster energy
expectation. Our experiment result indicates that the proposed method provides lowest energy
consumption per new accepted device while compared with schemes with full network-assisted and
independent device discovery in low numbers of new device arrival (for the number of new devices
arrival = 1 ~ 3).
Determining the Optimum Number of Paths for Realization of Multi-path Routing...
This document proposes an algorithm for determining the optimal number of paths for multi-path routing in MPLS-TE networks. The algorithm involves:
1. Constructing a network graph and finding the set of shortest paths between nodes using Dijkstra's algorithm.
2. Determining the maximum flow that can be transmitted over each shortest path based on the minimum cut using the Ford-Fulkerson theorem.
3. Considering delay as another criterion and formulating the problem as a multi-criteria optimization to maximize flow while minimizing delay.
4. Defining a utility function to reduce the problem to a single-criterion by representing the quality of criteria on a 0 to 1 scale.

A cross layer delay-aware multipath routing algorithm for mobile adhoc networks
Mobile Ad Hoc Networks (MANETS) require reliable routing and Quality of Service(QoS)
mechanism to support diverse applications with varying and stringent requirements. Routing
protocols such as AODV, AOMDV, DSR and OLSR use minimum hop count as the metric for
path selection, hence are not suitable for delay sensitive real time applications. To support such
applications delay constrained routing protocols are employed. These Protocols makes path
selection based on the delay over the discovered links during routing discovery and routing
table calculations. We propose a variation of a node-disjoint Multipath QoS Routing protocol
called Cross Layer Delay aware Node Disjoint Multipath AODV (CLDM-AODV) based on
delay constraint. It employs cross-layer communications between MAC and routing layers to
achieve link and channel-awareness. It regularly updates the path status in terms of lowest
delay incurred at each intermediate node. Performance of the proposed protocol is compared
with single path AODV and NDMR protocols. Proposed CLDM-AODV is superior in terms of
better packet delivery and reduced overhead between intermediate nodes.
Robustness Analysis of Buffer Based Routing Algorithms in Wireless Mesh Network
Robustness Analysis of Buffer Based Routing Algorithms in Wireless Mesh NetworkAssociation of Scientists, Developers and Faculties
Wireless Mesh Network rose as a promising innovation for providing quick and productive communication for which numerous algorithms have been proposed in networking infrastructure. For routing there are various performance parameters such as throughput, network congestion, resiliency, fairness, robustness, network jitter, delay, stability, optimality, simplicity, completeness etc. Robustness provides the capability to deal with all the failures that come across during the connection in the network to increase the network performance. In this paper we have studied and analyzed three algorithms namely on robustness parameter Resilient multicasting [2], Resilient Opportunistic Mesh Routing for Wireless Mesh Network (ROMER) [3], and Buffer Based Routing (BBR) [4], in Wireless Mesh Networks. Analysis through various parameters such as network congestion, network throughput and resiliency [5], shows network performance of BBR is better.Bandwidth guaranteed
Computer network is becoming more popular and common, the need to use the broadband connection services (e-learning - online training, video conferencing - online conference, IPTV - digital TV ...) of organizations and individuals is increasing. Multicast is an effective mechanism for the transmission of information and data to many recipients simultaneously. Multicast is a routing problem from a source node to a receiver node set, also known as the routing from one point to multipoint. The advances in technology and multimedia applications emerge quickly has provided great motivation for the application of new real-time multi-point. Many multi-point applications will not function properly if the QoS (quality of service) can not be guaranteed. Therefore, multi-point algorithms must be able to meet the QoS constraints (cost, reliability, bandwidth, jitter, delay...). The objective of multicast routing algorithms guarantee QoS is to provide routing algorithms have the ability to recognize the tree to satisfy the maximum of traffic streams with QoS requirements. Most multicast algorithms on MPLS (MultiProtocol Label Switching) considered the unique QoS constraint as bandwidth. The other QoS constraints can be converted into bandwidth efficiency. Starting from this reality, this paper research multicast routing algorithms guarantee bandwidth and propose new algorithm compares with existing ones.

The document analyzes the performance of five routing protocols - AOMDV, DSDV, AODV, DSR, and OLSR - in a mobile ad hoc network (MANET) environment based on the variable number of nodes. The protocols were simulated and their performance was evaluated based on three metrics: throughput, packet delivery ratio, and end-to-end delay. The results showed that AODV outperformed the other protocols in most scenarios, achieving higher throughput and packet delivery ratio. AODV was able to establish stronger paths between source and destination nodes, reducing packet loss.
A comparative analysis on routing
This document presents a comparative analysis of three routing protocols for mobile ad hoc networks (MANETs): AODV, DSR, and OLSR. It analyzes the performance of these protocols under different scenarios varying node mobility, network load, and node density. The key metrics examined are throughput, end-to-end delay, routing overhead, and network load. The analysis found that OLSR generally had the highest throughput and AODV and OLSR introduced less delay than DSR. DSR introduced the highest routing overhead, while protocols performed similarly under varying network loads.

Ad hoc Networks
This document analyzes the impact of varying transmission range, mobility speed, and number of nodes on the performance of three routing protocols (AODV, DSDV, DSR) in mobile ad hoc networks. It simulates these protocols using the NS-2 simulator and measures the performance based on several QoS metrics including packet delivery ratio, end-to-end delay, routing overhead, and throughput. The results show that AODV generally has the best packet delivery ratio and throughput, while DSDV has the lowest end-to-end delay. DSR performance is between AODV and DSDV. Increasing the transmission range and number of nodes tends to improve performance, while increasing mobility reduces it.
Analysis of Random Based Mobility Model using TCP Traffic for AODV and DSDV M...
In Mobile Ad hoc network (MANETS), no fixed infrastructure is available. Different wireless hosts are free to move from one location to another without any centralized administration, so, the topology changes rapidly or unpredictably. Every node operates as router as well as an end system. Routing in MANETs has been a challenging task ever since the wireless networks came into existence. The major reason for this is continues changes in network topology because of high degree of node mobility. The MANET routing protocols have mainly two classes: Proactive routing (or table-driven routing) protocols and Reactive routing (or on-demand routing) protocols. In this paper, we have analyzed various Random based mobility models: Random Waypoint model, Random Walk model, Random Direction model and Probabilistic Random Walk model using AODV and DSDV protocols in Network Simulator (NS 2.35). The performance comparison of MANET mobility models have been analyzed by varying number of nodes using traffic TCP. The comparative conclusions are drawn on the basis of various performance metrics such as: Routing Overhead (packets), Packet Delivery Fraction (%), Normalized Routing Load, Average End-to-End Delay (milliseconds) and Packet Loss (%).

Fuzzy Controller Based Stable Routes with Lifetime Prediction in MANETs
In ad hoc networks, the nodes are dynamically and arbitrary located in a manner that the interconnections between nodes are changing frequently. Thus, designing an effective routing protocol is a critical issue. In this paper, we propose a fuzzy based routing method that selects the most stable route (FSRS) considering the number of intermediate nodes, packet queue occupancy, and internodes distances. Also it takes the produced cost of the selected route as an input to another fuzzy controller predicts its lifetime (FRLP), the evaluation of the proposed method is performed using OMNet++4.0 simulator in terms of packet delivery ratio, average end-to-end delay and normalized routing load.
Packet Loss Rate Differentiation in slotted Optical Packet Switching OCDM/WDM
We propose a multi-class mechanism for Optical Code Division Multiplexing (OCDM), Wavelength
Division Multiplexing (WDM) Optical Packet Switch (OPS) architecture capable of supporting Quality of Service
(QoS) transmission. OCDM/WDM has been proposed as a competitive hybrid switching technology to
support the next generation optical Internet. This paper addresses performance issues in the slotted OPS
networks and proposed four differentiation schemes to support Quality of Service. In addition, we present a
comparison between the proposed schemes as well as, a simulation scheduler design which can be suitable
for the core switch node in OPS networks. Using software simulations the performance of our algorithm in
terms of losing probability, the packet delay, and scalability is evaluated.
Improved Good put using Harvest-Then-Transmit Protocol for Video Transfer
In multiple wireless networks, large end-to-end delay and packet losses can decrease meaningfully the traffic flow goodput due to path irregularity and multiplicity. To report these problems, current methods are proposed by using management of queue and decision making process. Hence, this paper proposesa Harvest-Then-Transmit (HTT) Protocol which selects an energy efficient path based on multiple parameters i.e. energy, delay, transmission time and perform transmission of video to handle number of video packets. A multipath environment is establishing where a server performs transferring of video along the energy efficient path of wireless network. Simulation shows the proposed protocol improves the overall goodput up to 10%, increases packet delivery rate up to 12%, and reduces end-to-end delay up to 3%, compared to existing system.

Towards Seamless TCP Congestion Avoidance in Multiprotocol Environments
In this paper we explore the area of congestion
avoidance in computer networks. We provide a brief overview
of the current state of the art in congestion avoidance and also
list our extension to the TCP congestion avoidance mechanism.
This extension was previously published on an international
forum and in this paper we describe an improved version which
allows multiprotocol support. We list preliminary results
carried out in a simulation environment.
New introduced approach called Advanced Notification
Congestion System (ACNS) allows TCP flows prioritization
based on the TCP flow age and priority carried in the header
of the network layer protocol. The aim of this approach is to
provide more bandwidth for young and high prioritized TCP
flows by means of penalizing old greedy flows with a low
priority. Using ACNS, substantial network performance
increase can be achieved.
Performance analysis of manet routing protocol in presence
This document analyzes the performance of different routing protocols in a mobile ad hoc network (MANET) under hybrid traffic conditions. It simulates a MANET with 50 nodes moving at speeds up to 20 m/s using the AODV, DSDV, and DSR routing protocols. Traffic included both constant bit rate and variable bit rate sources. Results found that AODV had lower average end-to-end delay and higher packet delivery ratios than DSDV and DSR as the percentage of variable bit rate traffic increased. AODV also performed comparably under both low and high node mobility scenarios with hybrid traffic.
A Load Aware Proposal for Maximum Available Bandwidth Routing in Wireless Mes...
This document summarizes a load aware proposal for maximum available bandwidth routing in wireless mesh networks. It first introduces wireless mesh networks and discusses that seeking maximum available bandwidth paths is a fundamental routing issue. It then analyzes several existing routing techniques that provide bandwidth guarantees, including ETX, AVAIL, EED, and CAB. ETX considers packet loss ratios, AVAIL models 802.11 MAC behavior to predict throughput and delay, EED accounts for queuing delay, and CAB satisfies consistency requirements through hop-by-hop routing. The document identifies problems with these existing methods and proposes a load aware routing protocol to route through maximum available bandwidth paths while satisfying optimality and consistency requirements. It will plot throughput and delay graphs
An Extensive Literature Review of Various Routing Protocols in Delay Tolerant...
This document summarizes an extensive literature review on routing protocols in delay tolerant networks (DTNs). It begins by defining DTNs as wireless networks with intermittent connectivity where nodes use a store-carry-forward mechanism. Common routing protocols for DTNs like epidemic, spray and wait, and prophet are described. The document then reviews several papers that propose and evaluate new routing algorithms or improvements for DTNs, analyzing metrics like delivery ratio, overhead, and latency. Key factors considered include node contact histories, social characteristics, energy constraints, and message prioritization. Finally, it suggests the contact duration between nodes could be an important parameter to further optimize routing in DTNs.
Achieving Optimum Value of k in a K-fold Multicast Network with Buffer using ...
Multicast network is widely used for effective communication, transmission and performance
optimizations of a network. In this paper, a new model has been developed to determine a
suitable value of the fold k of a k-fold multicast network under different traffic loads under
Poisson traffic with finite queue at each node. We have derived stationary distribution for the
network states and then derived expressions for the network throughput and the blocking
probability of the network. It has been found in this research work that the network throughput
increases very fast as we increase the fold number. However, at a certain value of the fold, the
blocking probability ceases to increase and it remains constant. We have also observed that as
the offered traffic is increased, the throughput also increases. Moreover, the system parameter k
is increased, the blocking probability decreases. However, after an optimum value of k, the
blocking probability remains constant for a particular value of the offered traffic. In fact, in this
paper, by evaluating the performance of a k-fold multicast network, our developed model improves the performance of a multicast network.
PERFORMANCE COMPARISION OF DSDV, AODV AND DSRFOR MOBILE AD HOC NETWORK BY VAR...
This document compares the performance of three routing protocols - DSDV, AODV, and DSR - for mobile ad hoc networks by simulating networks of varying sizes using the Qualnet simulator. The main findings are that AODV performed most efficiently for network sizes of 30, 40, and 50 nodes, and that performance decreased for all three protocols as the number of nodes increased. For a network of 50 nodes, the three protocols exhibited different performance levels at different node counts.
Dsr aodv performance
This document analyzes the performance of two on-demand routing protocols (AODV and DSR) in mobile ad hoc networks with varying network sizes up to 50 nodes. It simulates the protocols using the NS-2 network simulator and measures performance metrics like packet delivery fraction, end-to-end delay, normalized routing load, and throughput. The results show that the differences in AODV and DSR protocol mechanics lead to significant variations in performance for different network densities.
DIFFERENTIATED SERVICES ENSURING QOS ON INTERNET
Differentiated Services is the most advanced method for traffic management which provides QoS. QoS is
essential for today’s internet. QoS represents set of techniques necessary to manage throughput, packet
loss and delay. Traffic Conditioners or Policers are the most important components of differentiated
services. In this research, different Traffic Conditioners or Policers are compared on the basis of QoS
parameters (Performance metrics) which are throughput, packet loss and delay to provide QoS on internet.
Traffic classification and traffic conditioning are important functions of differentiated services also known
as admission control which are governed by service level agreement (SLA). Traffic classification and traffic
conditioning is done by traffic conditioners at edge routers. Goal of this research is to choose the best
Traffic Conditioner to apply from source to destination pair because only one traffic conditioner can be
applied from source to destination so that QoS can be guaranteed.

- It proposes a novel solution that integrates mobile ad hoc networks (MANETs) to improve delivery of high priority real-time application data over low latency MANET paths.
- Experimental results showed the proposed approach was effective in reducing network overhead and congestion, while also improving routing protocol performance in terms of packet delay and throughput.

The document describes an improved PIN entry method to prevent shoulder surfing attacks. The basic BW method divides numbers between two colored halves in each round. An observer can group entries over rounds to determine a PIN digit. The improved method displays four random colors across ten digit keys in each round. Users enter based on their PIN digit's color. This prevents grouping as colors randomly change, securing PINs even from skilled observers. The method uses sets and permutations to partition colors after each entry.

This document describes a genetic algorithm approach for automatically generating fuzzy rules for classification problems. The genetic algorithm uses rule importance as the fitness criteria, calculated as the rule's support for each class. The algorithm encodes rules using fuzzy membership set numbers for antecedents and consequents. It iterates for a set number of generations or until a minimum number of rules are fired, selecting high-fitness rules to generate offspring via crossover. The offspring replace lower-fitness rules, and the new rule population is evaluated in the next generation. The approach aims to consistently generate optimal fuzzy rules for classification using genetic search.

Ad hoc Networks
This document analyzes the impact of varying transmission range, mobility speed, and number of nodes on the performance of three routing protocols (AODV, DSDV, DSR) in mobile ad hoc networks. It simulates these protocols using the NS-2 simulator and measures the performance based on several QoS metrics including packet delivery ratio, end-to-end delay, routing overhead, and throughput. The results show that AODV generally has the best packet delivery ratio and throughput, while DSDV has the lowest end-to-end delay. DSR performance is between AODV and DSDV. Increasing the transmission range and number of nodes tends to improve performance, while increasing mobility reduces it.
Analysis of Random Based Mobility Model using TCP Traffic for AODV and DSDV M...
In Mobile Ad hoc network (MANETS), no fixed infrastructure is available. Different wireless hosts are free to move from one location to another without any centralized administration, so, the topology changes rapidly or unpredictably. Every node operates as router as well as an end system. Routing in MANETs has been a challenging task ever since the wireless networks came into existence. The major reason for this is continues changes in network topology because of high degree of node mobility. The MANET routing protocols have mainly two classes: Proactive routing (or table-driven routing) protocols and Reactive routing (or on-demand routing) protocols. In this paper, we have analyzed various Random based mobility models: Random Waypoint model, Random Walk model, Random Direction model and Probabilistic Random Walk model using AODV and DSDV protocols in Network Simulator (NS 2.35). The performance comparison of MANET mobility models have been analyzed by varying number of nodes using traffic TCP. The comparative conclusions are drawn on the basis of various performance metrics such as: Routing Overhead (packets), Packet Delivery Fraction (%), Normalized Routing Load, Average End-to-End Delay (milliseconds) and Packet Loss (%).

Fuzzy Controller Based Stable Routes with Lifetime Prediction in MANETs
In ad hoc networks, the nodes are dynamically and arbitrary located in a manner that the interconnections between nodes are changing frequently. Thus, designing an effective routing protocol is a critical issue. In this paper, we propose a fuzzy based routing method that selects the most stable route (FSRS) considering the number of intermediate nodes, packet queue occupancy, and internodes distances. Also it takes the produced cost of the selected route as an input to another fuzzy controller predicts its lifetime (FRLP), the evaluation of the proposed method is performed using OMNet++4.0 simulator in terms of packet delivery ratio, average end-to-end delay and normalized routing load.

Improved Good put using Harvest-Then-Transmit Protocol for Video Transfer
In multiple wireless networks, large end-to-end delay and packet losses can decrease meaningfully the traffic flow goodput due to path irregularity and multiplicity. To report these problems, current methods are proposed by using management of queue and decision making process. Hence, this paper proposesa Harvest-Then-Transmit (HTT) Protocol which selects an energy efficient path based on multiple parameters i.e. energy, delay, transmission time and perform transmission of video to handle number of video packets. A multipath environment is establishing where a server performs transferring of video along the energy efficient path of wireless network. Simulation shows the proposed protocol improves the overall goodput up to 10%, increases packet delivery rate up to 12%, and reduces end-to-end delay up to 3%, compared to existing system.

Towards Seamless TCP Congestion Avoidance in Multiprotocol Environments
In this paper we explore the area of congestion
avoidance in computer networks. We provide a brief overview
of the current state of the art in congestion avoidance and also
list our extension to the TCP congestion avoidance mechanism.
This extension was previously published on an international
forum and in this paper we describe an improved version which
allows multiprotocol support. We list preliminary results
carried out in a simulation environment.
New introduced approach called Advanced Notification
Congestion System (ACNS) allows TCP flows prioritization
based on the TCP flow age and priority carried in the header
of the network layer protocol. The aim of this approach is to
provide more bandwidth for young and high prioritized TCP
flows by means of penalizing old greedy flows with a low
priority. Using ACNS, substantial network performance
increase can be achieved.
Performance analysis of manet routing protocol in presence
This document analyzes the performance of different routing protocols in a mobile ad hoc network (MANET) under hybrid traffic conditions. It simulates a MANET with 50 nodes moving at speeds up to 20 m/s using the AODV, DSDV, and DSR routing protocols. Traffic included both constant bit rate and variable bit rate sources. Results found that AODV had lower average end-to-end delay and higher packet delivery ratios than DSDV and DSR as the percentage of variable bit rate traffic increased. AODV also performed comparably under both low and high node mobility scenarios with hybrid traffic.
A Load Aware Proposal for Maximum Available Bandwidth Routing in Wireless Mes...
This document summarizes a load aware proposal for maximum available bandwidth routing in wireless mesh networks. It first introduces wireless mesh networks and discusses that seeking maximum available bandwidth paths is a fundamental routing issue. It then analyzes several existing routing techniques that provide bandwidth guarantees, including ETX, AVAIL, EED, and CAB. ETX considers packet loss ratios, AVAIL models 802.11 MAC behavior to predict throughput and delay, EED accounts for queuing delay, and CAB satisfies consistency requirements through hop-by-hop routing. The document identifies problems with these existing methods and proposes a load aware routing protocol to route through maximum available bandwidth paths while satisfying optimality and consistency requirements. It will plot throughput and delay graphs

This document summarizes an extensive literature review on routing protocols in delay tolerant networks (DTNs). It begins by defining DTNs as wireless networks with intermittent connectivity where nodes use a store-carry-forward mechanism. Common routing protocols for DTNs like epidemic, spray and wait, and prophet are described. The document then reviews several papers that propose and evaluate new routing algorithms or improvements for DTNs, analyzing metrics like delivery ratio, overhead, and latency. Key factors considered include node contact histories, social characteristics, energy constraints, and message prioritization. Finally, it suggests the contact duration between nodes could be an important parameter to further optimize routing in DTNs.
Achieving Optimum Value of k in a K-fold Multicast Network with Buffer using ...
Multicast network is widely used for effective communication, transmission and performance
optimizations of a network. In this paper, a new model has been developed to determine a
suitable value of the fold k of a k-fold multicast network under different traffic loads under
Poisson traffic with finite queue at each node. We have derived stationary distribution for the
network states and then derived expressions for the network throughput and the blocking
probability of the network. It has been found in this research work that the network throughput
increases very fast as we increase the fold number. However, at a certain value of the fold, the
blocking probability ceases to increase and it remains constant. We have also observed that as
the offered traffic is increased, the throughput also increases. Moreover, the system parameter k
is increased, the blocking probability decreases. However, after an optimum value of k, the
blocking probability remains constant for a particular value of the offered traffic. In fact, in this
paper, by evaluating the performance of a k-fold multicast network, our developed model improves the performance of a multicast network.

This document compares the performance of three routing protocols - DSDV, AODV, and DSR - for mobile ad hoc networks by simulating networks of varying sizes using the Qualnet simulator. The main findings are that AODV performed most efficiently for network sizes of 30, 40, and 50 nodes, and that performance decreased for all three protocols as the number of nodes increased. For a network of 50 nodes, the three protocols exhibited different performance levels at different node counts.

The results show that the differences in AODV and DSR protocol mechanics lead to significant variations in performance for different network densities.
DIFFERENTIATED SERVICES ENSURING QOS ON INTERNET
Differentiated Services is the most advanced method for traffic management which provides QoS. QoS is
essential for today’s internet. QoS represents set of techniques necessary to manage throughput, packet
loss and delay. Traffic Conditioners or Policers are the most important components of differentiated
services. In this research, different Traffic Conditioners or Policers are compared on the basis of QoS
parameters (Performance metrics) which are throughput, packet loss and delay to provide QoS on internet.
Traffic classification and traffic conditioning are important functions of differentiated services also known
as admission control which are governed by service level agreement (SLA). Traffic classification and traffic
conditioning is done by traffic conditioners at edge routers. Goal of this research is to choose the best
Traffic Conditioner to apply from source to destination pair because only one traffic conditioner can be
applied from source to destination so that QoS can be guaranteed.

Wireless Network Security Architecture with Blowfish Encryption Model
Abstract: In this research paper ,we developed a model for a large network, wireless nodes are interconnected and each can be considered as a node processor that offer services to other node processors connected to a specific network. A very high proportion of the nodes that offer services need to carry out an authentication process so as to make an access request to the node offering the service. In this context, an integrated reconfigurable network security architecture moved to the application layer has become the need of the day for secure wireless data sharing. The security schemes of the seven layer OSI architecture need to be placed intrinsically in the wireless node itself and should be capable of supporting the MAC layer, IP address based layer and the routing protocols of the network layer. This work focuses on the use of emulator and embedded hardware architectures for wireless network security. In this work, the individual nodes can have a unique security signature pattern maintained by respective wireless nodes using an encryption algorithm and this is made dynamic. The metrics includes latency, throughput, Scalability, Effects of data transfer operation on node processor and application data located in the processor Keywords:Wireless Network security, Embedded hardware, Reconfigurable architecture, blowfish algorithm

load, throughput and retransmission.A COMPARATIVE ANALYSIS ON ROUTING PROTOCOLS OF MOBILE AD HOC NETWORK
In this modern era, Mobile Ad hoc Network (MANET) is widely used for its mobility and self-configuring
features. Hence, a better security approach is needed for maintaining high level network performance in
mobile ad hoc network. This paper presents the comparative analysis of quality of service (QoS) of MANET
protocols. In this regard, three types of most widely used protocols, named, Ad hoc On-demand Distance

been used to analyze. Therefore, AODV is selected in distributed ad hoc setting for the path discovery.
Also, AODV is a reactive improvement of Dynamic Destination Sequence Vector (DSDV) protocol. On the
other hand, the number of route broadcast is decreased by source routes on demand in AODV, which is
opposite of DSDV algorithm. In this research, the quality of service parameters of network paths are also
included to develop trust in the links to defend from various attacks. Moreover, a comparative analysis of
delay, congestion, packet losses, transit time between source and destination is illustrated on AODV and

The protocols are evaluated under different node speeds on a grid topology network with 90 nodes over an area of 1500x1500 meters. Simulation results show that AODV generally performs best in terms of throughput and packet delivery ratio across varying node speeds, while FSR performs worst for these metrics. IERP shows the worst performance for average end-to-end delay and average jitter as node speed increases.

This document discusses routing metrics for wireless mesh networks (WMNs). It begins by introducing WMNs and noting that routing protocol efficiency depends on the routing metrics used. It then:
1) Defines a network model for a WMN connected to a global network with static routers, a gateway router, and mobile clients.
2) Studies existing routing metrics, including characteristics metrics should have and classifications of unicast versus multicast metrics.
3) Discusses several unicast routing metrics that could be suitable for WMNs, including hop count, expected number of transmissions, expected transmission duration, and per-hop round trip time.
Abstract + Poster (MSc Thesis)
The document summarizes research on evaluating the performance of routing protocols (RPs) for mobile ad hoc networks (MANETs). The research involved simulating 3 RPs - AODV, DSR and OLSR - under different networking scenarios to analyze their performance. Key findings include: OLSR had the highest throughput but also the largest control overhead, making AODV better suited for environments with energy/bandwidth constraints. Varying node density, mobility and traffic loads impacted protocol performance. The research aims to validate RP features and provide guidance on protocol selection for different MANET conditions.

In the recent past, wireless sensor networks have been introduced to use in many applications. To design the networks, the factors needed to be considered are the coverage area, mobility, power consumption, communication capabilities etc. The challenging goal of our project is to create a simulator to support the wireless sensor network simulation. The network simulator (NS-2) which supports both wire and wireless networks is implemented to be used with the wireless sensor network.Performance analysis of aodv with the constraints of varying terrain area and...
Mobile Ad Hoc Networks (MANETs) are wireless networks,
where there is no requirement for any infrastructure support to
transfer data packets between mobile nodes. These nodes
communicate in a multi-hop mode; each mobile node acts
both as a host and router. The main job of Quality of Service
(QoS)[1][2] routing in MANETs is to search and establish
routes among different mobile nodes for satisfying QoS
requirements of wireless sensor networks as PDR, Average
end-to-end delay, Average Throughput. The QoS routing
protocols efficient for commercial, real-time and multimedia
applications are in demand for day to day activities[2].
Performance analysis of aodv with the constraints of
This document summarizes a research paper that analyzed the performance of the AODV routing protocol in wireless sensor networks under different terrain area sizes and pause times using the NS-3 simulator. The researchers found that packet delivery ratio remained nearly constant for small terrain areas but decreased for larger areas. Average throughput decreased with larger terrain areas, while average delay remained nearly constant for small areas but increased for larger ones. The paper concludes that AODV has better performance in networks with high mobility and size and is preferred for real-time traffic over other protocols like DSR and DSDV.

The GUI interface facilitates changing parameters and visualizing the transmitted and received OFDM frames, spectra, and constellations. Simulation results demonstrate the variation in performance between modulation techniques in different channel conditions.
Optimize the Network Coding Paths to Enhance the Coding Protection in Wireles...
Efficient protection techniques for multimedia data transfer over Wireless Sensor Network (WSN) are very essential issues. In noisy Wireless Multimedia Sensor Networks (WMSN) Quality of Service (QoS) is a challenging task due to bandwidth and limited energy, and unpredictable channel conditions. Therefore, Forward Error Correction (FEC), a class of channel coding has been widely used in WSN. Nevertheless, the bulky size of multimedia data makes it more difficult to be transported over the noisy multi-hop wireless network. Moreover, the efficiency of FEC drops as the number of hops increases. In this paper, an optimized protection technique based on network coding and rateless code has been proposed to enhance the throughput and reduce overhead during data transfer in WMSN. The performance of NCP-OPR is enhanced via Optimal Network Path Model (ONPM) where the best available paths are optimally selected using Particle Swarm Optimization (PSO). In conjunction with the proposed protection scheme, the proposed ONPM is intended for limited power WSN by optimally distributing the power usage among the network paths so that the throughput can be improved.

Video steaming Throughput Performance Analysis over LTE
This document analyzes the video streaming throughput performance over LTE networks using the OPNET simulation tool. It simulates two scenarios: 1) downlink and uplink video conferencing with static users and 2) the same with users moving at 30m/s. The key metrics measured are packet delay variation and end-to-end delay. The results show that static users experience higher packet delay variation than mobile users, likely due to increased traffic accumulation. End-to-end delay is also higher for static users compared to those moving at 30m/s.

This document analyzes the performance of a neighbor knowledge based broadcast protocol called BCAST in mobile ad hoc networks using network simulator NS-2. It varies the number of data senders (multicast group size) and data sending rate to analyze packet delivery ratio, end-to-end delay, packet loss probability, and network control overhead. The simulation results show that BCAST generally performs well and provides robust performance even with high traffic loads.
Analysis of Neighbor Knowledge Based Bcast Protocol Performance For Multihop ...
Reliable group communication is a challenging issue for most Mobile Ad-hoc Networks (MANETs) due to
dynamic nature of wireless mobile nodes, group key establishment and management, ensuring secure
information exchange and Quality of Service (QoS) in data transfer. Recently multicast and broadcast
routing protocols are emerging for supporting QoS aware group communication. In MANETs QoS
requirements can be quantified by a set of measurable pre-specified service attributes such as packet
delivery ratio, end-to-end delay, packet loss probability, network control overhead, throughput,
bandwidth, power consumption, service coverage area etc. In this paper, the performance of a neighbor
knowledge based broadcast protocol is analyzed using different QoS metrics (packet delivery ratio, end-toend delay, packet loss probability and network control overhead). BCAST is used as broadcast protocol.
The performance differentials are analyzed using NS-2 network simulator for varying number of data
senders (multicast group size) and data sending rate (offered traffic to the network) over QoS aware group
communication. Simulation results show that BCAST performs well in most cases and provides robust
performance even with high traffic environments.
Study on Performance of Simulation Analysis on Multimedia Network
This document summarizes a study that simulated voice communication over wired networks using the NS-2 network simulator. The study modeled VoIP traffic between nodes using the SCTP protocol and added background traffic to evaluate its effects. Key findings from the simulation included:
1) Average latency was 0.98 seconds and 98 packets were dropped, indicating degraded performance when background traffic was added.
2) Average jitter (packet delay variation) was calculated to be 0.006 seconds, showing instability in the network with changing traffic patterns.
3) A graph of latency over time demonstrated increased delays and bottlenecks as background traffic overloaded network links.

This document analyzes the performance of various modulation schemes for achieving energy efficient communication over fading channels in wireless sensor networks. It finds that for long transmission distances, low-order modulations like BPSK are optimal due to their lower SNR requirements. However, as transmission distance decreases, higher-order modulations like 16-QAM and 64-QAM become more optimal since they can transmit more bits per symbol, outweighing their higher SNR needs. Simulations show lifetime extensions up to 550% are possible in short-range networks by using higher-order modulations instead of just BPSK. The optimal modulation depends on transmission distance and balancing the energy used by electronic components versus power amplifiers.

1) The document simulates and compares the performance of AODV and DSDV routing protocols in a mobile ad hoc network under three conditions: when users are fixed, when users move towards the base station, and when users move away from the base station.
2) The results show that both protocols have higher packet delivery and lower packet loss when users are either fixed or moving towards the base station, since signal strength is better in those scenarios. Performance degrades when users move away from the base station due to weaker signals.
3) AODV generally has better performance than DSDV, with higher throughput and packet delivery rates observed across the different user mobility conditions.

The document proposes a hybrid technique using Anisotropic Scale Invariant Feature Transform (A-SIFT) and Robust Ensemble Support Vector Machine (RESVM) to accurately identify faces in images. A-SIFT improves upon traditional SIFT by applying anisotropic scaling to extract richer directional keypoints. Keypoints are processed with RESVM and hypothesis testing to increase accuracy above 95% by repeatedly reprocessing images until the threshold is met. The technique was tested on similar and different facial images and achieved better results than SIFT in retrieval time and reduced keypoints.

This document studies the effects of dielectric superstrate thickness on microstrip patch antenna parameters. Three types of probes-fed patch antennas (rectangular, circular, and square) were designed to operate at 2.4 GHz using Arlondiclad 880 substrate. The antennas were tested with and without an Arlondiclad 880 superstrate of varying thicknesses. It was found that adding a superstrate slightly degraded performance by lowering the resonant frequency and increasing return loss and VSWR, while decreasing bandwidth and gain. Specifically, increasing the superstrate thickness or dielectric constant resulted in greater changes to the antenna parameters.

This document summarizes a research paper that presents a speech enhancement method using stationary wavelet transform. The method first classifies speech into voiced, unvoiced, and silence regions based on short-time energy. It then applies different thresholding techniques to the wavelet coefficients of each region - modified hard thresholding for voiced speech, semi-soft thresholding for unvoiced speech, and setting coefficients to zero for silence. Experimental results using speech from the TIMIT database corrupted with white Gaussian noise at various SNR levels show improved performance over other popular denoising methods.

This document discusses group consumption modes. It analyzes factors that impact group consumption, including external environmental factors like technological developments enabling new forms of online and offline interactions, as well as internal motivational factors at both the group and individual level. The document then proposes that group consumption modes can be divided into four types based on two dimensions: vertical (group relationship intensity) and horizontal (consumption action period). These four types are instrument-oriented, information-oriented, enjoyment-oriented, and relationship-oriented consumption modes. Finally, the document notes that consumption modes are dynamic and can evolve over time.

All antennas were mounted on an FR4 substrate. The effects of adding different slot patterns to the ground plane on resonance frequency, bandwidth, gain and efficiency were analyzed parametrically. Key findings were that reshaping the patch and adding slots increased bandwidth and shifted resonance frequency. The elliptical and star patches in particular performed better than the conventional design. Three antenna configurations were selected for fabrication and measurement based on the simulations: a conventional patch with a slot under the patch, an elliptical patch with slots

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Abstract: The computer networks have evolved themselves into an altogether new generation with Mobile Ad- Hoc networks. The Mobile Ad-Hoc Networks are increasingly becoming more sophisticated and complex in terms of topology, routing and security[1][2][3]The new age MANETs incorporate routing of heavier traffic classes like audio, video and multimedia. It has become important to study the performance characteristics of the multimedia traffic class in MANETS [10] that includes packet loss rate and throughput. In this paper we will discuss these performance parameter throughput under different scenarios like varying Bandwidth, channel error rate, delay and fragment size. Keywords: MANET, Packet loss rate, Throughput, Bandwidth, Fragment size I. Introduction In this paper we present a relatively complex network with both UDP and TCP traffic flowing in the network. If we study the performance of UDP traffic class in a network, it becomes easier to predict the behaviour of multimedia traffic class as it will be sent over the UDP in the simulations[9] We analyse the UDP traffic on the main router to router link for the following parameters. Throughput: Throughput or network throughput is number of bits delivered successfully per second to the destination. It is the sum of bits received successfully by all destinations.This data may be delivered over a physical or logical link. The throughput is measured in bits per second (bps). Mathematically, it can be defined as: Throughput= N/1000 Where N is the number of bits which is received successfully by all destinations [4] II. Methodology The primary traffic class that multimedia adopts is UDP. IN multimedia communication for MPEG-4 traffic, if we analyse the characteristics of UDP traffic for throughput and other network performance parameters then we can predict the behaviour of MPEG-4 also in a network with multi-class traffic. For this purpose a n/w generating both TCP and UDP traffic classes is created and tested. The topology of the network created is as follows:
- 2. Analysis of Multimedia Traffic Performance in a Multi-Class traffic environment for UDP traffic www.iosrjournals.org 29 | Page The network has 2 source nodes (S1 and S2), one generating TCP traffic and the other generating UDP traffic to be transferred at the destination node (d) [7][8] The network parameters are changed on the link (r1-r2) as shown in the figure. The following parameters are changed in the network. In first case, the bandwidth of the main router to router link (r1-r2) is changed keeping the other network parameters unchanged. In the second scenario the delay of the main router to router link (r1-r2) is changed keeping the other network parameters unchanged. In the third scenario the error rate of the main link is changed and in the fourth scenario the packet size is changed. The result that we present is the effect of fragment size on THROUGHPUT. We have kept the delay to be constant and analysed with varying bandwidths and error rate. We observed the throughput for different fragment sizes at 10 ms, 50ms and 100ms delay Fig 1:Analysis of Throughput at various fragment sizes for varying delays and Bandwidths for 10 ms Delay Fig 2:Analysis of Throughput at various fragment sizes for varying delays and Bandwidths for 50 ms Delay 0 50000 100000 150000 200000 250000 300000 350000 400000 450000 0.2 0.4 0.6 0.2 0.4 0.6 0.2 0.4 0.6 throughput(bps) channel error rate Throughput for Fragment sizes 256, 512, 1000 at 10ms delay 0.3 0.9 1.5 0 50000 100000 150000 200000 250000 300000 350000 400000 450000 0.2 0.4 0.6 0.2 0.4 0.6 0.2 0.4 0.6 throughput(bps) channel error rate Throughput for Fragment sizes 256, 512,1000 at 50ms delay 0.3 0.9 1.5

Conclusion and Future scope In this paper we find out the effect of different fragment sizes having varying bandwidth, delays and channel error rate on the throughput based on above topology. The results reveal that the throughput increases as the fragment size increases at lower error rates and throughput decreases when the fragment size increases at higher error rates. The results may facilitate careful optimization of multimedia traffic over UDP. The behaviour of UDP traffic largely depend upon the fragment size. The effect of fragment size on throughput for varying bandwidth, delay and channel error rate provides a complete estimation of traffic control. References [1] S. P. Alampalayam, A. Kumar, and S.
