摘　　要：服务质量保障(QoS)是设计Ad Hoc网络的必备环节,QoS路由算法对于Ad Hoc网络有重要意义。本文提出了一种Ad Hoc网络QoS多径按需路由算法QMRA,该算法采用移动预测计算链路的生存时间,应用能量模型获得链路的剩余能量,然后综合链路生存时间和剩余能量两种因素来计算链路质量,并选择链路质量大的路径转发分组。仿真结果表明:与AOMDV算法相比,QMRA算法提高了网络的生命周期与数据发送成功率,降低了网络的平均端对端延迟。QoS is an essential procedure for Ad Hoc network design and QoS routing algorithm is important to Ad Hoc network. The paper puts forward QoS multipath routing algorithm QMRA under Ad Hoc network. The algorithm calculates survival time of link by movement forecasting and applies energy module to get remaining energy of link. Then it calculates link mass by integrating two factors： link survival time and remaining energy, and selects the path with greater mass in link to transmit it to the sub-group. The simulation result shows that QMRA algorithm can increase the life cycle of network and effective data transmission rate, and decrease the average end-to-end delay of network when compared with AOMDV.
