摘要： DYMO是Ad Hoc网络中一种动态的按需路由协议，本质上属于单径路由协议，而多径路由能更好地支持QoS。首先分析了DYMO协议的优点及存在的问题，在此基础上将DYMO和服务质量QoS及多径路由结合起来，提出一种新的QoS感知的多径DYMO路由协议QA-DYMO，利用多条链路不相交路径来发送数据，并提出一种QoS感知的路由算法。该协议能够适应网络的动态变化和较好地支持QoS。仿真结果表明，该协议要优于其他相关的协议。
关键词: Ad Hoc网络，DYMO，多径路由，服务质量
Abstract: DYMO is a dynamic on-demand routing protocol in mobile ad hoc networks, which is a singlcpath routing protocol. But multi-path routing can support QoS better than single-path routing. Firstly, the advantages and problems of DYMO protocol were analyzed. Then a novel QoS-aware multi-path DYMO routing protocol(QA-DYMO) was proposed to provide QoS and multi path routing which establishes and utilizes multiple routes of link-disjoint paths to send data packets concurrently. Finally, a QoS-aware routing algorithm was proposed. QA-DYMO can adapt to the dynamic changes of the network and support QoS better. The simulation results show that the proposed protocol outperforms other pertinent protocols.
