无线Ad hoc网络是一种不需要基础设施的自组织和自管理网络,网络中所有的节点同时具有终端和路由器的功能。因此网络可以通过节点路由发现机制转发分组,并进行路由维护。文中对DSR(动态源路由协议)的路由发现过程进行了优化,并采用OPNET仿真软件对基于DSR协议的Ad hoc网络的路由开销和时延等关键参数进行了仿真统计,分析了改进后的路由协议对网络质量的影响。
Ad hoc wireless network is a self-organizing and self-managing network that does not need infrastructure. All nodes in the network have the functions of terminals and routers at the same time. Therefore, the network can forward the packet through the node route discovery mechanism and maintain the route. In this paper, DSR (Dynamic Source Routing Protocol) route discovery process is optimized, and OPNET simulation software is used to simulate the key parameters such as routing overhead and delay of Ad hoc network based on DSR protocol. The improved routing The impact of the agreement on network quality.
