摘要: 在移动自组织网络动态源路由(DSR)协议的基础上,设计一种基于差异能耗率的路由协议。在路由发现阶段,将节点能量门限值和差异能耗率引入到路由代价的计算中,按其拓扑结构和路径上各节点的能耗率选择合适的传输路径,使数据包在各个路径上均衡通过,从而延长整个网络的存活时间。仿真结果表明,与DSR和REECV协议相比,该协议在死亡节点数、网络生存时间、投递率方面的性能较好。

Abstract: The paper utilizes the Dynamic Source Routing(DSR) protocol in Mobile Ad-hoc Networks(MANET) to design a node protocol based on diversity in energy consumption. It introduces the energy threshold and the diversity energy consumption into the calculation of the path cost in the route discovery phase, and it selects the appropriate transmission path according to topological structure and energy consumption of each node in the path. So that the data packets can through different paths on balance, to extend the survival time of the entire network. Simulation results show that, compared with the classic DSR protocol and REECV protocol, the proposed protocol has a certain improvement in the performance indicators of the death of nodes, network lifetime and delivery rate.

Key words: Mobile Ad-hoc Networks(MANET), Dynamic Source Routing(DSR) protocol, diversity, energy-saving, delay, energy threshold
