摘要： 通过分析Chord协议，提出基于多环的Chord改进算法MR-Chord。MR-Chord采用多环和组相结合的结构，在组内每个节点记录全组的路由，组与组之间以递归算法相连成多个环。通过理论分析和仿真实验对Chord和MR-Chord进行比较，结果表明，MR-Chord使系统的性能和适应性更好，路由表中的冗余很少。

Abstract: By analyzing Chord protocol, this paper proposes an improved Chord algorithm called MR-Chord(Chord Based on the Combination of Ring and Group), which is based on multi-ring. MR-Chord uses the structure combining multi-ring and group. Each node in the group records the whole routing of the group and the groups link into multi-ring with recursive algorithm. Analysis on theory and simulation results show that MR-Chord has better performance and adaptability of the system, and the routing tables have few redundancy.
