一种改进的非结构化P2P网络资源搜索策略

An improved unstructured P2P network resources searching strategy

非结构化P2P网络具有资源搜索效率不高,容易产生大量冗余信息等问题,为此,提出了一种改进的资源搜索策略。通过为网络中的节点建立朋友节点来改进传统的非结构化对等网络资源搜索,并在此基础上设计了一种新的资源搜索算法。仿真试验证明,该策略在一定程度上提高了非结构化P2P资源搜索的效率,同时减少了网络中的冗余信息量。

The low effieiency of resources searching and information redundancy is the main problems of unstructured P2P network. To resolve this problem, an advanced resource searching strategy is given in this paper. Through establishing friend-nodes in the net to improve the traditional unstructured P2P network resources searching, and on this basis, a new resources searching algorithm is designed. The simulation shows that the strategy can improve the resources searching efficiency of unstructured P2P network, while reducing the information redundancy in the net.
