摘要： 动态源路由(DSR)协议能较好适用中小型对等自组网络环境，但在非对等网络环境中面临一定应用局限。针对该问题，分析DSR协议的特点和存在问题，结合非对等环境和层次路由思想，提出新的协议CDSR，对CDSR路由协议进行性能评估。仿真结果表明，该协议具有较好的执行效能，可提升网络性能。

Abstract: Dynamic Source Routing(DSR) protocol is well applied to small and medium-sized ad hoc network environment. There are certain limitations to use not well in non-peer-to-peer network environment. This paper analyzes the characteristics and problems on DSR protocol. A new routing protocol, CDSR, is proposed with combined non-peer-to-peer environment and hiberarchy routing strategy. Simulation results about CDSR’s performance evaluation show that algorithm has better performance and can improve network capability.

Key words: Ad Hoc network, Dynamic Source Routing(DSR) protocol, core code, tree topology
