Ad Hoc网络多径源路由协议的实现和性能评价

Implementation and Performance Evaluation of Multi-path Source Routing Protocol in Wireless Ad Hoc Network

针对AdHoc网络中路由协议问题,介绍了无线AdHoc网络中的一种基于动态源路由(DSR)的新型路由协议———多径源路由(MSR)的基本概念,给出了在Linux(kernel2.4.7)操作系统上完成的MSR协议实现及实现中涉及的几个关键算法.在5个结点组成的MSR实验床上做了几组实验并对实测数据进行分析.得到的性能评价结果表明,MSR协议可以为AdHoc网络结点间通信提供支持,特别是在结点处于快速运动状态下,MSR协议能够改善网络的传输质量.

Some basic concepts on wireless Ad Hoc multi-path source routing (MSR) protocol,were introduced. The implementation of MSR under Linux, completed by the authors, was also presented and some key algorithms in the implementation were given. Some experiments were done on a test-bed consisting of five mobile nodes. The performance evaluation of MSR in terms of the test-bed was conducted and some performance results were achieved. The main conclusion is that MSR can provide better support for mobile communications especially in fast movement environment.
