摘　　要：随着多媒体应用的发展,在移动自组网中提供具有服务质量的多播越来越重要。本文基于MAODV协议,提出了一种新的保障服务质量的多播路由协议。该协议在改进HELLO包测试带宽方法的基础上以能量作为约束条件,定义了以带宽、时延、能量为参数的路由选择函数,修改了原MAODV协议的路由发现机制。网络仿真结果表明,在网络节点移动速度较大和网络负载较重的情况下,Q-MAODV协议的包交付率和生存时间优于原MAODV协议。Along with the development of muhimedia applications, it becomes more and more important to provide QoS multicast in Ad Hoc networks. The Q-MAODV protocol was proposed based on the original MAODV protocol in this paper. It improved the method of acquiring bandwidth using HELLO packets and raked？energy？as a？ constraint, defined a new routing metric by taking bandwidth, delay and energy into account and modified the routing discovery mechanism. Simulation results show that under the con- dition of heavy loads and fast movement of the nodes, the delivery ratio and the network＇s lifetime of the improved protocol is better than the old ones.
