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.

DYMO is a dynamic on-demand routing protocol in mobile ad hoc networks, which is a single-path 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 call adapt to the dynamic changes of the network and support QoS better. The simulation results show that the proposed protocol outperforms other pertinent protocols.
