Abstract

Abstract: DYMO（Dynamic MANET On-Demand） is a reactive on-demand routing protocol in mobile ad hoc networks，which is a single-path routing protocol.But multi-path routing can improve network performance better than single-path routing.Firstly，the advantages and problems of DYMO protocol are analyzed.Then an improved DYMO routing protocol（I-DYMO） is proposed to support multi-path routing which utilizes multiple routes of link-disjoint paths to send data.Finally，the protocol is combined with source routing.The simulation results show that it improves the packet delivery fraction and reduces the average end-to-end delay and has good stability in mobile scenes.

摘要： DYMO（Dynamic MANET On-Demand）是Ad Hoc 网络中一种反应式按需路由协议，本质上属于单径路由协议，而多径路由能更好地提高网络性能。首先分析了DYMO协议的优点及存在的问题，在此基础上将DYMO和多径路由结合起来，提出了一种改进的DYMO路由协议I-DYMO，利用多条链路不相交路径来发送数据，并将之与源路由结合起来。仿真结果表明该协议提高了分组投递率并降低了端到端平均时延，在动态移动环境下具有较好的稳定性。
