A New Incentive Scheduling Mechanism for Live Video Streaming in Mesh-Based P2P Networks

Peer to peer networks offer an extensible framework for supporting video streaming service over the Internet. P2P networks efficiency highly depends on peers' contribution. In practice, some peers only use the service, but share few resources or do not share any resources. This phenomenon is called free riding which seriously affects the P2P networks efficiency. So, in order to encourage the peers to contribute and share their resources in P2P networks, using of incentive mechanisms seems necessary. In this paper, we propose an incentive-based scheduling method for live video streaming in mesh-based P2P networks. In proposed strategy the amount of contribution of the peers is measured and kept in a distributed manner. In addition, we suggest an improved scheduling method in which peers are served based on their contribution. Simulation results show positive effect of proposed approach on total performance of the network in terms of delay and frame loss.
