摘要
在某无线专用通信网的背景下,分析研究了MIL_STD_188_220C路由协议的性能及其特点,并用OMNeT++进行仿真。通过仿真实验对220C的路由协议进行一些改进,在拓扑更新机制中利用增量消息技术,通过缩减拓扑更新包的体积来减小拓扑变化时的收敛时间和路由开销;采取自适应调整拓扑更新分组发送间隔的方法提高了分组传输成功率,优化了网络的性能,更加适于实际应用。
Under the background of a wireless communication network, the MIL _ STD _ 188 _ 220C is simulated by OMNeT ＋＋ to get its performance as well as its characteristics. Based on the result of simulation, some improvement of the routing protocol is given. Increment message technique is used in topology update system to reduce the convergence time and the routing overhead when the topology of network is changed by reducing the size of the topology update packet. The MIN _ UP _ PER parameter can be adjusted adaptively to improve the success ratio of packet delivery, thus the performance of the network is improved.
