Abstract: An optimization scheme to AODV protocol based on location information in Ad-hoc networks is examined and proposed.This scheme controls the transmission power and uses regional broadcast.Results obtained by Network Simulation（NS） show that the optimized AODV scheme performs effectively in enhancing packet transfer rate and shortening network time delay，meanwhile it avoids affecting other Ad hoc network parameters.

摘要： 研究并提出了一种基于位置信息的AODV路由协议的优化方案。它通过动态调整传输功率，使用区域概率广播的两种方法进行优化。经NS仿真后的性能分析比较，在保证不降低其他网络性能的前提下，改进的AODV协议可以有效地提高传输成功率并缩短端到端的网络延时。
