摘　　要：通过搭建Ad hoc无线自组织网络实验平台进行多次室外测试。对接收信号功率强度的变化分析得出节点传输范围的变化特征及其对路由协议性能的影响。对分组投递率的测量得出Ad hoc网络投递率与节点间距离的关系。根据路由切换现象分析了Ad hoc网络运行过程中出现的路由不稳定现象的成因。最后给出了相应的解决方案。Lots of tests in several aspects in outdoor environment by establishing a wireless Ad hoc network experiment platform are organized. The relationship between network delivery ratio and the node＇s transmission was obtained from the measurement of grouping the delivery ratio, which exactly explained the unstable routing behavior in wireless multi-hop environment. Through a large amount work and distance between nodes was obtained. The routing of tests, the relationship between delivery rate of netprotocol＇ s inherent problem is analyzed through route changes based on testing software. Finally several solutions to this problem are put forward.
