基于Chord算法的研究与改进

Research and Improvement of Chord Algorithm

由于Chord算法在选择路由时并未考虑结点间的物理拓扑关系，消息转发的路由跳数只是基于逻辑特性而跟物理位置无关，而提高系统的网络性能的关键则正是减少消息转发的跳数。本文根据小世界网络的启发，通过对Chord算法的研究，分析了结构化网络各种算法的优缺点，提出了一种基于Chord算法的优化和改进。

The Chord algorithm did not consider in the choice of routes between nodes when the physical topology, message routing hops forward characteristics is based on logic has nothing to do with the physical location,and improve network performance is the key to reduce the message is forwarded hop number.Based on small world network,inspired by Chord algorithm to analyze the structure of the network advantages and disadvantages of each algorithm,a method based on the optimization and improvement of Chord.
