| 摘 要： | 无线自组网是由一组无线移动主机组成的无基础设施的临时网络,在与其相关的网络协议的研究中常涉及到修改及扩展问题。文章分析了经典按需路由协议AODV的路由发现和建立过程,通过NS2仿真软件的内核扩展及重编译,在控制台输出相关的扩展内容,包括RREQ和RREP包的传送、正反向路由表的建立和节点路由表的更新等信息。结果表明,在NS2仿真软件下对无线自组网路由协议的研究和调试分析是一种科学有效的方法。最后对AODV协议本身提出了几种改进的思路和方法。

| Abstract: | Mobile Ad Hoc Network（MANET） is a temporary network constructed by a collection of wireless mobile nodes without infrastructures,and its network protocol research often involves modification and expansion.We analyze the route discovery and building process of classic on-demand routing protocol AODV.Through the kernel extension and recompiling of NS2 simulation software,the corresponding expansion contents are output on the console,including RREQ and RREP packets transmission,positive and negative routing table establishment,node routing table update and other information.The results show that it is a scientific and effective method to study,debug and analyze MANET routing protocol under NS2 simulation software.Finally several improvement ideas and methods are proposed for AODV protocol. |
