Peer-to-Peer Adaptive Forward Error Correction in Live Video Streaming over Wireless Mesh Network

Recently, Peer-to-Peer (P2P) video streaming over multi-hop wireless networks such as Wireless Mesh Networks (WMNs) has been of great interest among users. Although low implementation/maintenance cost, high network throughput, easy implementation, self-configuration and self-healing make WMNs as a suitable infrastructure for multimedia streaming, providing high level of Quality-of-Service (QoS) remains as an open issue. QoS improvement is an important and fundamental problem in P2P live video streaming over WMNs. In order to address this issue, this study proposes an efficient adaptive hybrid Forward Error Correction (FEC) P2P video loss recovery method with low overhead. We formulate the problem as a residual loss probability and show that an adaptive distributed method can significantly reduce video distortion and end-to-end delay while it reduces the imposed overhead due to data protection. Also the comprehensive simulation results show that the proposed method provides high video quality in comparison with other analyzed methods.
