无线自组织网络(Ad Hoc Network)作为一种对等无线网络,在军事、传感器网络等众多场合有着极其重要的应用。动态源路由(DSR)协议是Ad Hoc网络最经典的协议之一,当前大多数对DSR协议的改进措施都是基于仿真环境得出,而在实际环境下往往没有起到预期的效果。在实际的无线环境下,用基于嵌入式终端组成Ad Hoc网络,首先对实际测试中的问题进行分析研究,然后提出了本地回复机制的改进措施,同时针对无线环境的多样性,对于DSR路由协议各参数依赖关系给出了一些论述,最后通过实际测试对比说明这些措施是行之有效的。
Ad Hoc Network As a peer-to-peer wireless network, it has an extremely important application in many occasions such as military and sensor networks. Dynamic Source Routing (DSR) protocol is one of the most classical protocols in Ad Hoc networks. At present, most of the improvements to DSR protocol are based on simulation environment, but often do not work as expected in real environment. In the real wireless environment, based on the embedded terminal composed of Ad Hoc network, firstly, the problems in the actual test are analyzed and studied, and then the improvement measures of the local reply mechanism are put forward. At the same time, in view of the diversity of wireless environment, for the DSR routing protocol Some parameters are given the relationship between the arguments, and finally through the actual test contrast shows that these measures are effective.
