P2P网络中抑制节点自私性的拓扑调整方法设计与实现

Because of the incomparable advantages in scalability, robustness, cost-effective, and load balancing, P2P network is being more and more concerned and researched. However, the phenomenon that selfish peers thumb a lift and malicious peers upload untrustworthy files widely exists, which have become one of the serious restraint to P2P File Sharing System's improvement. This text implements a P2P mutually beneficial simulation system, whose topology adjustment algorithm is based upon a mutually beneficial ability. The topology adjustment algorithm fully considers mutually beneficial ability, adjusts the connections between the peers dynamically, assembles the peers whose mutually beneficial ability is high, and push out the poor ability peers.
