In recent years, video streaming over wireless mesh networks (WMNs) has been of great interest among the users. In WMNs, although node mobility and scalability are the two most important well-known advantages by end-users, they can decrease the perceived video quality on receivers with increasing the probability of path failure, especially when the number(More)
In recent years, Random Network Coding (RNC) has emerged as a promising solution for efficient Peer-to-Peer (P2P) video multicasting over the Internet. This probably refers to this fact that RNC noticeably increases the error resiliency and throughput of the network. However, high transmission overhead arising from sending large coefficients vector as(More)
In the recent years, video and audio streaming have been very popular in the Internet and accounts for excessive traffic not only in the Internet, but also in many private networks. Transferring this amount of traffic needs both reliable and high performance infrastructure as well as efficient approaches to increase bandwidth utilization. Real-time playback(More)
In the recent years, multimedia streaming has been really popular among end users, especially live video streaming over the Internet. However, video streaming applications need efficient and reliable methods for disseminating video frames in the networks. Although Mesh-based Peer-to-Peer (P2P) networks make the system more robustness against link failures,(More)
As randomnetwork coding (RNC) considerably increases the network throughput, it has been of great interest for video streaming over wireless mesh networks (WMNs). However, mobile video users suffer from high transmission overhead due to the transmission of large coefficient vectors as headers and an excessive imposed decoding computational complexity due to(More)
The purpose of this research is to design an efficient network coding based architecture for peertopeer live video streaming over mesh-based networks (wired and wireless) such that it can provide high video quality on peers. Moreover, three main objectives of this research for providing smooth video playback in meshbased P2P live video streaming system can(More)
In the recent years, Wireless Mesh Networks (WMNs) has become popular for video multicasting. Although peer-to-peer communication lets wireless nodes improves the functionality of the video streaming applications over WMNs, required level of Quality-of-Service (QoS) is one of the most important challenges in these systems. Therefore, it is necessary to(More)
Wireless Mesh Networks (WMNs) cannot completely guarantee good performance of traffic sources such as video streaming. To improve the network performance, this study proposes an efficient engineering solution named Wireless-to-Ethernet-Mesh-Portal-Passageway (WEMPP) that allows effective use of wired communication in WMNs. WEMPP permits transmitting data(More)
