摘　　要：研讨了AdHoc网络中具有QoS约束的多播路由问题和网络模型,提出了一种基于延伸MAODV(Multicast AdHoc On-demand Distance Vector)多播路由协议的延时、带宽和包丢失率等度量的QoS多播路由协议。仿真实验显示该协议较好地改进了端到端传输延时、带宽利用率和传输性能,为AdHoc网络QoS多播路由提供了一种新的有效途径。This paper discusses the multicast routing problem with multiple QoS constraints, which may deal with the delay, bandwidth and packet loss measurements, and describes a network model for researching the Ad Hoc network QoS multicast routing problem. It presents a complete solution for QoS routing based on an extension of the MAODV routing protocol that deals with delay, bandwidth and packet loss measurements. The solution is based on lower layer specifics. Simulation results show that, with the proposed QoS Multicast routing protocol, end-to-end delay and bandwidth on a route can be improved in most of eases. It is an available approach to multicast routing decision with multiple QoS constraints.
