摘　　要：随着多媒体应用的不断发展,在Ad Hoc网络中提供QoS保证具有重要的意义。在研究节点拥塞、节点碰撞等本地信息对QoS路由影响的基础上,提出了一种在Ad Hoc网络中提供QoS保证的路由协议——基于本地信息的QoS-aware多径路由协议QAMR。该协议把带宽作为QoS参数,通过引入节点利用因子和路径利用因子来考虑可行路径处理能力问题和对业务的QoS保证。该协议的路由发现和路由维护算法是DSR协议的扩展。通过仿真和对比分析验证了QAMR协议无论在静态网络和动态网络,都具有很好的性能。With the great development of multimedia applications, providing QoS guarantee for Ad Hoc networks is very important. Based on the analysis of local information such as node congestion, node collision impacting on QoS routing, the QoS-aware Multipath Routing （QAMR） Protocol based on local information was proposed to provide QoS guarantee for Ad Hoc networks. The protocol takes bandwidth as the QoS parameter, and considers handling capaci（y of effective paths and guaranteeing QoS of service by introducing node utilization factor and path utilization factor. The algorithm of route discovery/maintenance in the protocol is just extension of DSR protocol. Simulation result and analysis show that the QAMR protocol has good performance in either static topology or dynamic topology.
