【摘要】 无线Ad Hoc网络的路由算法是Ad Hoc网络的核心技术之一．Ad Hoc网络具有动态拓扑的特点,主要表现为网络节点数目和节点运动导致网络拓扑结构变化．为研究Ad Hoc网络规模和拓扑变化对分组投递率、时延、路由控制开销等性能的影响,采用Opnet软件进行仿真．结果表明Ad Hoc网络拓扑和规模变化时,从时延、收包率、路由控制等方面综合考虑,选择动态源路由协议算法较为理想．更多还原

【Abstract】 The routing arithmetic of wireless Ad Hoc network is one of the key technologies of wireless Ad Hoc network. The Ad Hoc network has the characteristics of dynamic topology. It is embodied in the number of nodes and the change of topology caused by the nodes’ moving. In order to study the net scale of Ad Hoc and the effect of topological changes on delivery rate, time delay and routing control spending, simulation is conducted by adopting Opnet. The simulation results show that when Ad Hoc network topology and scale change, the selection of dynamic routing protocol is optimal, taking delay, packet arrival rate and routing control into consideration.更多还原
