Multi-source Multi-cast P2P Streaming Delivery in Wireless Mesh Networks

Wireless interference makes simultaneous use of some adjacent links impossible,it is impractical to adopt the P2P streaming delivery scheme used in conventional wired networks to wireless mesh networks.In order to improve the quality of P2P streaming delivery over wireless mesh networks,by integrating the wireless interference model and media streaming rate-distortion model into consideration,the cross-layer multi-source multi-path multicast scheme is proposed and the genetic algorithm is employed to implement the scheme.Comparing to the multi-source multi-path unicast scheme,the multi-source multi-path multicast scheme adopts the wireless networks' character that the data is transmitted by broadcasting and can effectively decrease the streaming transmitting interfering probability.The simulation results shows that the multi-source multi-path multicast scheme can effectively decrease the total rate-distortion of P2P media streaming delivery over wireless mesh networks by comparing to the multi-source multi-path unicast scheme.
