摘要:
Adhoc网络是一种没有中心基础设施、节点间可自由通信的无线对等网络。它的网络性能受网络拓扑变化的影响非常大。为了明确无线信道的衰落特性对其网络性能造成的影响，文章用实际测试的方法对其进行了详细研究。通过搭建无线自组织网络实验平台进行了多次室外测试，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
Abstract:
Ad hoc networks are wireless p2p network without infrastructure in which nodes can freely exchange messages. The network performances are greatly affected by its topologies. In order to specify the wireless channel＇s fading effect on Ad hoc network performances, here adopt practice testing method. It organized lots of tests in several aspects in outdoor environment by establishing a wireless Ad hoc network experiment platform. 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 of tests, the relationship between delivery rate of network and distance between nodes was obtained. The routing protocol＇s inherent problem is analyzed through route changes based on testing software. Finally severai solutions to this problem is put forward
