基于Kleinberg模型的P2P网络搜索协议
P2P network search protocol based on Kleinberg model
摘要
Abstract
In order to solve such problems as low routing efficiency and load imbalance existing in structurized P2P networks based on DHT technology,a structurized P2P network protocol was designed according to Kleinberg small world model.The P2P network is composed of some node clusters which are mutually connected,and there exist either short-range links or long-range links between the node clusters.The proposed protocol has certain small world characteristics,which decreases the average path length of search routing.The P2P network load can be balanced through setting the maximum value of internal node number of node clusters.The spending of P2P network search was analyzed.An upper bound existed for the average path length of P2P network search based on Kleinberg small world model.The experimental results show that with increasing the network scale,the average search path length increases in a logarithm function mode.With increasing the number of long-range links,the average search path length can be reduced,and the decreasing trend shows as an inverse ratio function mode.关键词
