为了提高网络的查询速度,降低查询成本,近年来小世界理论被引入P2P网络,并通过构建远程连接提高网络的查询性能.本文主要研究了P2P网络中远程连接的构建问题,并根据实际网络中查询对象的分布,提出了一种基于历史信息构建远程连接的方式.本文通过仿真实验分析比较了三种远程连接的构建方式,结果显示基于历史信息选择远程连接的方式,可以在实际P2P网络具有更短的平均查询路径长度,更低的构建和维护成本以及良好的鲁棒性.
In order to improve the query speed of the network and reduce the query cost, the theory of small world has been introduced into P2P network in recent years, and the query performance of the network has been improved by constructing remote connections.This paper mainly studies the construction of remote connections in P2P networks, Query the distribution of objects and put forward a way to construct remote connection based on historical information.This paper analyzes and compares the construction methods of three kinds of remote connections by simulation experiment and the results show that the remote connection can be selected based on the historical information, Shorter average query path length, lower build and maintenance costs, and good robustness.
