对等网络免费搭车反制机制改进方案的研究

Research in improving framework of counteracting free-riding in peer-to-peer networks

提出了一种分布式方案以降低免费搭车行为对对等网络的不利影响。方案中每个节点都是检测节点,负责监测其邻居,如果某个邻居节点存在免费搭车行为,检测节点将采取适当的反制行动。仿真结果表明这种反制机制能够降低免费搭车节点对系统造成的影响从而提高对等网络的性能。

This paper proposes a distributed framework to reduce the adverse effects of free riding on P2P network.This paper proposes a framework in which each peer monitors its neighbors,decides if they are free riders,and takes appropriate actions.The simulation results show that the framework can reduce the effects of free riding and can therefore increase the performance of a P2P network.
