MEVI is a multi-hop hierarchical routing protocol proposed for wireless multimedia sensor networks (WMSNs). It uses a cluster-based approach and opportunistic clustering to form clusters with minimal overhead. MEVI employs both intra-cluster and inter-cluster communication. During intra-cluster communication, non-cluster head nodes send sensed data to their cluster heads. For inter-cluster communication, cluster heads send aggregated data to the base station using multi-hop routing. MEVI selects routes based on a cross-layer approach considering link quality and energy parameters to improve energy efficiency and video quality delivery in WMSNs. Simulation results show that MEVI achieves longer network lifetime and better video quality compared to other routing protocols

Wireless sensor networks make use of sensor nodes distributed in a sensor node field. There are many factors that influence the sensor network design. Sensor networks have their own protocol stack aligned with the OSI model.
Wireless Sensor Networks (WSNs) are distributed and independent sensors that are connected and worked together to measure quantities such as temperature, humidity, pressure, noise levels or vibrations. WSNs can measure vehicular movement (velocity, location, etc.) and monitor conditions such as lightning condition, soil makeup and motion. Nowadays, WSNs are utilized in many common applications such as vehicle applications. Some of vehicle applications are: vehicle tracking and detection, tire pressure monitoring, vehicle speed detection, vehicle direction indicator, traffic control, reversing aid sensors etc. Such applications can be divided in major categories such as safety, security, environment and logistics. To implement WSN in an application and have an efficient system, we need to consider about WSN technology, and its components. This paper is aimed at providing reliable software architecture of WSN that could be implemented for better performance and working.
A WSN primary outline issue for a sensor system is protection of the vitality accessible at every sensor node. We propose to convey different, versatile base stations to delay the lifetime of the sensor system. We split the lifetime of the sensor system into equivalent stretches of time known as rounds. Base stations are migrated toward the begin of a round. Our strategy utilizes a whole number straight program to focus new areas for the base stations and in view of steering convention to guarantee vitality proficient directing amid every round. We propose four assessment measurements and look at our answer utilizing these measurements. Taking into account the reproduction results we demonstrate that utilizing various, versatile base stations as per the arrangement given by our plans would altogether expand the lifetime of the sensor system.
sensors are what we experience the most in our life. they are even working in our body in different aspects. they may be as eyes, ears, skin, tongue etc. when we combine them they make a network. it may be a human sensor network. but i have shared something interesting about wireless sensor networks.

EFFICIENT MULTI-PATH PROTOCOL FOR WIRELESS SENSOR NETWORKSijwmn
Wireless sensor networks are useful for streaming multimedia in infrastructure-free and hazardous environments. However, these networks are quite different from their wired counterpart and are composed of nodes with constrained bandwidth and energy. Multiple-path transmission is one of the methods for ensuring QoS routing in both wired and wireless environment. Directed diffusion, a well known wireless sensor network protocol, only routes packets through a single path, which barely meets the throughput requirement of multimedia data. Instead, we propose a multipath algorithm based on directed diffusion that reinforces multiple routes with high link quality and low latency. This algorithm retains the merits of the original directed diffusion algorithms, including its energy efficiency and scalability. A hybrid metric of link quality and latency is used as the criterion for path selection. In order to select disjoint paths, we propose a scheme for reinforced nodes to respond negatively to multiple reinforcement messages. We use the NS-2 simulation tool with video trace generated by Multiple Description Coding (MDC) to evaluate the performance. The results show that our algorithm gives better throughput and delay performance, i.e higher video quality, than standard directed diffusion that transmits over a single path, with low overheads and energy consumption.
In this contribution, we present selected novel approaches and results of our research work in the \ATHENA Christian Doppler Laboratory (Adaptive Streaming over HTTP and Emerging Networked Multimedia Services), a major research project at our department jointly funded by public sources and industry. By putting this work also into the context of related ongoing research activities, we aim at working out where HTTP Adaptive Streaming is currently heading.

Multicasting Of Adaptively-Encoded MPEG4 Over Qos-Cognizant IP NetworksEditor IJMTER
we propose a novel architectural planning for multicasting of adaptively-encoded
layered MPEG4 over a QoS-aware IP network. We re-quire a QoS-aware IP network in this case to
(1) Support priority dropping of packets in time of congestion. (2) Provide congestion notification to
the multicast sender. For the first requirement, we use RED's extension for service differentiation. It
recognizes the priority of packets when they need to be dropped and drops lower priority packets
first. We couple RED with our proposal for the second requirement which is the adoption of
Backward Explicit Congestion Notification (BECN) for use with IP multicast. BECN will provide
early congestion notification at the IP layer level to the video sender. BECN detects upcoming
congestion based on size of the RED queue in the routers. The MPEG4 adaptive-encoder can change
the sending rate and also can divide the video packets into lower priority packets and high priority
packets. Based on BECN messages from the routers, a simple flow controller at the sender sets the
rate for the adaptive MPEG4 encoder and also sets the ratio between the high priority and low
priority packets within the video stream. We use a TES model for generating the MPEG4 traffic that
is based on real video traces. Simulation results show that combining priority dropping, MPEG4
adaptive encoding, and multicast BECN: (1) Improves bandwidth utilization (2) Reduces time to
react to congestion and hence improves the received video quality (3) Maintains graceful degradation
in quality with congestion and provides minimum quality even if congestion persists.
QoS -Aware Spectrum Sharing for Multi-Channel Vehicular NetworkIJSRD
We consider QoS -aware band sharing in cognitive wireless networks where secondary users are allowed to access the band owned by a primary network provider. The intrusion from secondary users to primary users is forced to be below the tolerable limit. Also, signal to intrusion plus noise ratio (SINR) of each secondary user is maintained higher than a required level for QoS cover. When network load is high, admission control needs to be performed to satisfy both QoS and intrusion constraint. We propose an admission control algorithm which is performed jointly with power manage such that QoS needs of all admitted secondary users are satisfied while keeping the intrusion to primary users below the passable limit. When all secondary users can be supported at minimum rates, we allow them to increase their spread rates and share the spectrum in a fair manner. We formulate the joint power/rate allocation with max-min equality principle as an optimization problem. We show how to change it into a convex optimization problem so that its globally most favourable solution can be obtained. Numerical grades show that the proposed admission control algorithm achieves performance very close to the optimal solution.
Video traffic on the Internet is constantly growing; networked multimedia applications consume a predominant share of the available Internet bandwidth. A major technical breakthrough and enabler in multimedia systems research and of industrial networked multimedia services certainly was the HTTP Adaptive Streaming (HAS) technique. This resulted in the standardization of MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) which, together with HTTP Live Streaming (HLS), is widely used for multimedia delivery in today’s networks. Existing challenges in multimedia systems research deal with the trade-off between (i) the ever-increasing content complexity, (ii) various requirements with respect to time (most importantly, latency), and (iii) quality of experience (QoE). Optimizing towards one aspect usually negatively impacts at least one of the other two aspects if not both.
This situation sets the stage for our research work in the ATHENA Christian Doppler (CD) Laboratory (Adaptive Streaming over HTTP and Emerging Networked Multimedia Services; https://athena.itec.aau.at/), jointly funded by public sources and industry.
In this talk, we will present selected novel approaches and research results of the first year of the ATHENA CD Lab’s operation. We will highlight HAS-related research on: (i) multimedia content provisioning (machine learning for video encoding); (ii) multimedia content delivery (support of edge processing and virtualized network functions for video networking); (iii) multimedia content consumption and end-to-end aspects (player-triggered segment retransmissions to improve video playout quality); and (iv) novel QoE investigations (adaptive point cloud streaming). We will also put the work into the context of the international multimedia systems research.
DATA TRANSPARENT AUTHENTICATION USING QOD IN HYBRID NETWORKSEditor IJMTER
Hybrid networks are next generation of wireless networks that could be a
combination of Mobile wireless adhoc (MANET) networks and Wireless Infrastructure
networks. They are increasingly utilized in wireless communications that are extremely
supporting real time transmission with restricted Quality of Service. Invalid reservation and
race condition issues happens in MANET. In existing system, QoS-Oriented Distributed
routing protocol (QOD) is employed to boost the QoS support capability of hybrid networks,
it transforms the packet routing problem to resource scheduling problem that has 5
algorithms. They are, QoS guaranteed neighbor selection algorithm, Distributed packet
scheduling algorithm, Mobility based segment resizing algorithm, Traffic redundant
elimination algorithm and Data redundancy elimination based transmission algorithm. The
main drawback of hybrid networks is so far examined in minimum transmission hops and has
less beneficial feature with restricted number of mobile access points, mobility speeds, and
mobile workloads and with different network sizes. It will extremely perform on random
way point model and less in real mobility model. This paper present Data Transparent
Authentication to authenticates data streams by adjusting interpacket delay. Data Transparent
Authentication while not Communication overhead is an approach which reduces breakdown
of original information or sends out of band authentication data.
On Optimizing Resource Utilization in AVC-based Real-time Video StreamingAlpen-Adria-Universität
Real-time video streaming traffic and related applications have witnessed significant growth in recent years. However, this has been accompanied by some challenging issues, predominantly resource utilization. IP multicasting, as a solution to this problem, suffers from many problems. Using scalable video coding could not gain wide adoption in the industry, due to reduced compression efficiency and additional computational complexity. The emerging software-defined networking (SDN)and network function virtualization (NFV) paradigms enable re-searchers to cope with IP multicasting issues in novel ways. In this paper, by leveraging the SDN and NFV concepts, we introduce a cost-aware approach to provide advanced video coding (AVC)-based real-time video streaming services in the network. In this study, we use two types of virtualized network functions (VNFs): virtual reverse proxy (VRP) and virtual transcoder (VTF)functions. At the edge of the network, VRPs are responsible for collecting clients’ requests and sending them to an SDN controller. Then, executing a mixed-integer linear program (MILP) determines an optimal multicast tree from an appropriate set of video source servers to the optimal group of transcoders. The desired video is sent over the multicast tree. The VTFs transcode the received video segments and stream to the requested VRPs over unicast paths. To mitigate the time complexity of the proposed MILPmodel, we propose a heuristic algorithm that determines a near-optimal solution in a reasonable amount of time. Using theMiniNet emulator, we evaluate the proposed approach and show it achieves better performance in terms of cost and resource utilization in comparison with traditional multicast and unicast approaches.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Propose multi-hop using LQI, energy and hop count to select routes Increase the video quality, since it uses reliable routes MEVI, propose a scheme to create cluster which includes a minimal overhead – energy efficiency 12/01/08
12/01/08
MEVI relies on a hierarchical network architecture with heterogeneous nodes The nodes have heterogeneous capabilities and are divided into the following classes: (i) non-multimedia-aware nodes; and (ii) multimediaaware powerful nodes. CHs are used for routing, slot allocation, synchronizing non-CH transmissions, multimedia retrieval and data aggregation Non-multimedia-aware nodes are source nodes and multimedia-aware powerful nodes are destination nodes. 12/01/08
Simulations were carried out and repeated 20 times to have a confidence interval of 95%. For scenario 1 (small) use lower transmission power and for scenario 2 (bigger) user higher transmission power The Container video sequence with a QCIF resolution was chosen from the Video Trace Library. Container is the video with similar motion and complexity as expected for a fire detection system. 12/01/08
Shows the number of nodes per round that are still alive The number of nodes alive per round is same for MEVI in both versions, due to the fact that the main difference between them is that the multi-hop version includes a route discovery between CHs and BS. MEVI considers that CH are equipped with a alternative energy source Compared with LEACH, for Scenario 1, MEVI in both versions increased its network lifetime by 60%. The reason for this is that in LEACH the CH requires higher transmission power when it sends its packets to the BS, which consumes more energy. Additionally, MEVI reduces the signaling overhead to create clusters and considers two kinds of nodes 12/01/08
SSIM ranges from 0 to 1. higher value means better video quality VQM ranges fro 0 to 5, lower value means better performance. SD = Standard Deviation 12/01/08
SSIM ranges from 0 to 1. higher value means better video quality Single-hop protocols have almost the same video quality level. Since the transmitting nodes use the same transmission power at the same distance. However, MEVI multi-hop increases the video quality by 20% for SSIM and 40% for VQM. This is due to the fact that the proposed cross-layer solution selects reliable paths based on perceived network conditions. 12/01/08
VQM ranges fro 0 to 5, lower value means better performance. Single-hop protocols have almost the same video quality level. Since the transmitting nodes use the same transmission power at the same distance. However, MEVI multi-hop increases the video quality by 20% for SSIM and 40% for VQM. This is due to the fact that the proposed cross-layer solution selects reliable paths based on perceived network conditions. 12/01/08
The figure shows the video quality of a frame perceived by the user. The figure shows the Frame 266 SIM = 0.8 VQM = 1.0 SSIM = 0.5 VQM = 2.5 Thus, using QoE metrics, it is possible to get results more accurate related to the video quality from the user perspective 12/01/08
