动态源路由协议DSR在NDIS架构中的设计与实现

Design and implementation of dynamic sourcerouting protocol as NDIS intermediate driver

研究分析了基于Windows NDIS框架构建无线移动Ad hoc网络路由协议测试平台的一般方法,提出了以NDIS中间层驱动形式创建动态源路由协议(dynamic source routing,DSR)的设计方案,有效地解决了嵌入NDIS的DSR协议栈与Windows操作系统既有TCP/IP协议栈以及厂商网卡驱动之间的衔接与交互等关键问题,并最终完成了该DSR协议栈的实现。实验结果表明,该DSR协议栈的设计切实可行,通过在真实环境中的运行测试,为进一步分析研究DSR的安全、优化和应用提供了实体测试平台。

Real-world testing platform is very important to promote evaluation of MANET （ mobile Ad hoc network ） routing protocol. After researching and summarizing the general methods to construct MANET routing protocol stack through Windows NDIS（ network device interface specification） architecture, this paper proposed a scheme design to realize DSR （dynamic source routing） protocol through NDIS intermediate driver. This design resolved a series of key problems about cooperation between DSR and Windows inherent TCP/IP stack such as how to process ARP request packet, and also about the DSR inside functions＇ realization such as how to count time to resend DSR route request. Experiments results presente the feasibility of this design and implementation.
