摘要： 研究并提出了一种带路径收集机制的AODV协议优化方案，有效地结合了DSR协议的路径收集思想，在提高AODV协议运行效率的同时不会引入DSR协议运行开销大、可扩展性差等局限。经NS模拟后的性能分析比较，优化的AODV协议在提高分组发送成功率、降低路由开销、缩短端端延迟等方面效果显著。

Abstract: An optimization scheme to AODV protocol through path collection is examined and proposed. This scheme adopts the path collection mechanism in DSR protocol to improve the performance of AODV, meanwhile it avoids being affected by the high running overhead and weak scalability of DSR protocol. Results obtained by Network Simulation (NS) shows that the optimized AODV scheme performs effectively in terms of packet delivery ratio, routing overhead and end-to-end delay.
