摘　　要：Ad Hoc网络的服务质量模型中路由选择直接影响网络的可靠性和稳定性。将QoS-MSR多路径路由协议引入了无线移动网络无状态模型(SWAN),利用QoS-MSR的两个显著优点,即既在路由查找过程中带有QoS要求的信息又采用多分裂带宽预留机制(MBSR),有效地提高网络服务质量。仿真实验表明,在SWAN模型中采用QoS-MSR路由可以使网络的端到端时延、吞吐量和数据接收率等性能参数都有明显改善。Routing protocol plays an important role in the supports of QoS such as reliability and stability in the Stateless Wireless Ad Hoc Networks （SWAN） model for Ad Hoc networks. In this paper, a new protocol named Quality of Service- Muhipath Source Routing （QoS-MSR） multi-path routing was introduced into the SWAN model. It can effectively improve the quality of service by making the use of the two significant advantages of QoS-MSR that it can not only attach the information of QoS in the routing search process, but also adopt the algorithm of Multiple Bandwidth Splitting Reservation （MBSR）. Simulation results indicate that the performance parameters of the network （ end-to-end delay, throughput and the rates of data receiving） based on the adopted QoS-MSR in the SWAN model are remarkably improved.
