Research on Adhoc network routing is mainly to find a connected routing from the source to destination points. It often ignores the network QoS demand. If the data traffic exceed the network to be able to withstand the maximum, ad-hoc networks will not guarantee the flow of data transmission quality. Therefore, this paper proposes a improved QoS- AOMDV routing protocol in AOMDV routing. It adds certain restriction condition that consists of bandwidth, delay, hops and priority, which make routing node must meet QoS quirements when the phase of routing initation and routing maintenance. The simulation results show that the multi-path routing protocol can guarantee the quality of service of communication.%Ad-hoc网络路由主要研究从源和目的点之间找到一条连接的路由,经常忽略网络的QoS需求,如果数据流量超过了该网络所能承受的最大限度,Ad-hoc网络将不能保证数据流的传输质量.因此提出了一种改进的QoS-AOMDV路由协议,在AOMDV路由基础上增加了带宽、时延、跳数和优先级等约束条件,使得在路由发现和路由维护阶段满足一定的QoS需求.仿真结果显示,在多径路由协议可以保证通信服务质量.
