A Distributed Improvement Mechanism for Mesh-Based Peer-to- Peer Video-on-Demand Streaming

In P2P video streaming, the way of organizing peers in an overlay is one of the most important elements to achieve optimum use of system resources and better quality of service. For this purpose, the peers that they contribute more upload bandwidth, should located closer to the servers. This paper presents a distributed improvement mechanism to performmesh-based video-on-demand. This mechanism proposes a new method tolocatepeers withmore upload bandwidth, closer to the servers, with regard to playback points of them. The results of evaluating the proposed mechanism shows that our mechanism efficiently enhanced the quality of service parameters, and it is robustness in dynamic environments, the results also confirmed that our mechanism acts as an incentive mechanism.
