摘　　要：Ad Hoc网络是一种自组织的、由移动节点组成的、动态变化的多跳无线网络。该文首先对簇进行了介绍,并提出CD-SR是基于WCA的DSR路由协议;然后讲解了CDSR的主要设计思想:路由发现是在簇头之间进行的,簇间的通信需要借助于簇头(不存在网关);同时用G loMoS im模拟仿真工具,对CDSR与DSR的性能进行了分析和评价,并且得出CDSR协议较DSR协议具有高的投递率和吞吐率、低的延迟及较好的扩展性,更适合大规模自组无线网络;最后讨论了它的缺点。A mobile ad hoc network （MANET） is a self- organized and self- configured multi - hop wireless network, whose structure changes dynamically due to member mobility. The paper firstly introduces the cluster and brings forward a CDSR, which is based on the WCA and uses for reference the advantages of on - demand routing in DSR protocol. Then, it introduces CDSR. CDSR route discovery is realized from one Cluster Header to another and the communication between the Clusters recurs to Cluster Headers （no existing Gateway Node）. Meanwhile, it analyzes and evaluates the performances of CDSR routing protocol and DSR routing protocol under the GloMoSim simulator, comes to the conclusion that compared with DSR, the CDSR has the advantages of higher delivery rate and throughput, lower delay, better expansibility. Therefore, CDSR is more suitable for the large - scale self - organized wireless network. CDSR problems are discussed finally.
