摘要
Ad Hoc网络是由一些移动节点组成、拓扑结构复杂且动态变化的自组织网络。网络中没有固定的网络基础设施,对路由协议要求较高。通过在每个节点的路由表和发送接收包中增加能量参数等措施,提出基于AOMDV的多路径路由协议改进方案PE-AOMDV协议,最后在NS2仿真平台上实现对改进的AOMDV多路径路由协议仿真分析。仿真结果表明:与AOMDV协议相比,新的基于能量的多路径路由协议PE-AOMDV的传输时延和路由开销都有所降低,并提高了分组投递率,从而提高了网络性能。
Ad Hoc network is a self-organization network,and composed of many mobile nodes,its topological structure is complex and changes dynamically.As the network contains no fixed network infrastructure,thus requires fairly high routing protocol.On the basis of AOMDV protocol and by adding some energy parameters to the routing table of each node and the sending and receiving packets,a multipath routing protocol PE-AOMDV is proposed.Simulation on the platform NS-2 indicates that the proposed energy-based protocol PE-AOMDV has less transmission delay and routing consumption than the AOMDV protocol,could enhance the packet delivery rate,and thus improve the network performance.
