摘　　要：在比较分析Ad Hoc网络中现有QoS路由协议算法的基础上,改进了一种基于DSR具有QoS的路由协议(称为SRPQG协议)。在设计过程中把网络的稳定性作为主要目标,通过引入链路稳定因子,设计了新的提高链路稳定性的计算方法。此外,定义了新的函数进行路由开销综合评定,在数据流带宽保证的前提下,优先选择稳定性好的链路,从而网络的稳定性得到进一步保证。仿真结果表明,该协议在网络节点运动频繁或者节点数目较少时,表现出较好的QoS性能。Based on the existing QoS routing protocol,a routing protocol with the guaranted QoS is designed.The network stability is set as its primary target;by introducing the link stability factor,a new calculation method is designed.In addtion,a new function is designed to assess the routing overhead.When the demand of data flow bandwidth are met,stable links will be chosen,so it can guarantee the network stability.Then the protocol is simulated,and the results show that the protocol has good QoS guarantee when network node move frequently or node number is fewer.
