P2P VOD系统邻居节点查找算法
Neighbor search algorithm for P2P VoD system
摘要
Abstract
In P2P VoD(Video on Demand) system,it is difficult to find neighbors because the users' VCR operations are uncertainty .Aiming at this problem, a neighbor search algorithm based on prediction is proposed in this paper. A method based on virtual live channel is described to build the overlay,in which peers are organized by DHT(Distributed Hash Table) protocol. A learning prediction model based on users' behavior is proposed.According to the predicted results, the peer searches the neighbors in advance.The simulation results demonstrate that the algorithm can improve the VCR response latency and promote the peers' cooperation.关键词
