Wireless mesh network (WMN) technology operating on IEEE 802.11 standard is a wireless networkingtechnology consists of mesh routers and mesh clients, combined with the internet, mobile technology and sensor networks. Along with the development of technology and the increasing human needs, video transmission through wireless network becomes more important and necessary. Generally, the discussion of video transmission through wireless network is still in general, hence it provides a challenge in the use of throughput, end-to-end delay, packet loss and PSNR. Combined Scalable Video Coding (CSCV) is a new scheme for the development of H.264 / MPEG-4. In this research we use CSCV for video delivery with the IEEE 802.11 standard in WMN environment, which is applied to AODV, DSDV and DSR routing protocols. In order to obtain the performance of each protocol, we used testing metrics end-to-end delay, throughput, packet loss and PSNR. Simulator NS-2 is used for analysis and measurement of data. The results of simulation experiments conducted showed that AODV has the lowest end-to-end delay at 0.57 seconds, the DSR has a good value in the throughput at 31 kbps and PSNR at 22.7 dB, and DSDV has a low value in packet loss at 56.4%.

Flow Interference

Multi-radio wireless mesh network (MR-WMN) is one of the key access techniques in Mobile Internet. However, current 802.11-based MR-WMN is not able to provide low multicast end-to-end delay. To address this problem, we first propose a layered and analytical model by combining overlapping channel assignment with multi-path routing strategies. The proposed model can be used as a guide on multicast design. It decoupled multicast delay into transmission delay in the MAC layer and queuing delay in the Mesh layer based on that it derived a new multicast routing metric that had low end-to-end delay. Second, we prove that finding the minimum global flow interference solution is a NP-Complete problem an<I the relationship between global flow interference and network node densities is distributed in accord with double-Pareto lognormal (dP1N) distribution. Based on these two results, the DCA algorithm is proposed in order to minimum global flow interference which can efficiently reduce the multicast transmission delay in MAC layer. Last, to avoid the best wireless link being congested, we propose the flow adaptive-based MMRA algorithm by making use of the M R-M ED routing metric and the multi-path routing design philosophy, which took local channel congestion into account and can efficiently reduce the queuing delay in Mesh layer. Simulation result and comparison of the common algorithm MCM both show that the proposed model accurately characterizes the multicast delay in multi-radio wireless mesh network and the combination of the DCA and MMRA algorithms efficiently reduce the multicast end-to-end delay.

In wireless mesh network the nodes are dynamically self-organized and self- configured networks create a changing topology and keep a mesh connectivity to offer Internet access to the users. The shortest path problem is one of the most fundamental problems in networking. This problem can be solved by manytechniques and algorithm. In this paper we find the shortest path by using the fittest nodes in the network. By using the fittest node we can send the packets to the destination without packet loss, delay in packets.Average end to end delay is decreased by increasing bandwidth and the results are shown.

P2p Video Streaming

P2P video streaming combining SVC and MDC In this paper we propose and evaluate a combined SVC-MDC (Scalable Video Coding & Multiple Description Video Coding) video coding scheme for Peer-to-Peer (P2P) video multicast. The proposed scheme is based on a full cooperation established between the peer sites, which contribute their upload capacity during video distribution. The source site splits the video content into many small blocks and assigns each block to a single peer for redistribution. Our solution is implemented in a fully meshed P2P network in which peers are connected to each other via UDP (User Datagram Protocol) links. The video content is encoded by using the Scalable Video Coding (SVC) method. We present a flow control mechanism that allows us to optimize dynamically the overall throughput and to automatically adjust video quality for each peer. Thus, peers with different upload capacity receive different video quality. We also combine the SVC method with Multiple Description Coding (MDC) to alleviate the packet loss problem. We implemented and tested this approach in the PlanetLab infrastructure. The obtained results show that our solution achieves good performance and remarkable video quality in the presence of packet loss.
