摘　　要：Chord中的所有节点可视作分布在一维空间中,形成单一的环。针对移动Ad hoc网络,该文提出二维P2P的概念,将所有节点视作分布在二维平面内,允许多个可灵活配置的环存在,并提供冗余查询路径。基于此概念,该文还提出多环二维P2P资源发现协议族,并给出协议族中可行的环配置方案,证明其在网络直径和度性能上的改善。仿真结果表明,合理的配置环能明显改善基于移动Ad hoc网络的P2P查询性能。All nodes in Chord can be viewed as being placed into a one-dimensional ring. In this paper, a novel concept of bi-dimensional P2P is introduced for mobile Ad hoc networks, in which nodes are placed into a square, so that more than one configurable ring can be created, and redundant lookup routes can be provided. Based on the concept, the multi-ring bi-dimensional P2P lookup protocol family is .proposed. Applicable ring-configuration examples are provided and the performances are analyzed. Simulation results prove the performance improvement of the protocol family compared with Chord like protocols.
