摘　　要：通过分析Ad Hoc网络的特点及基于QoS的多播路由问题,提出了一种新的分布式多播路由算法。实验和分析的结果表明,文中构造的路由方案成功地解决了Ad Hoc网中基于QoS的多播路由问题。当Ad Hoc网络的拓扑结构改变不太快时,本文提出的路由方案不仅满足了实时业务对网络带宽和端到端延时的要求,优化了路由树的代价,而且有效地控制了算法的复杂性并可适用于大规模的网络中。*On the basis of analyzing the feature of Ad Hoc networks and their multicast routing with delay and bandwidth constrained, the paper presents a new distributed algorithm in Ad Hoc networks. Many experiments and analysis have been done to show that the routing mechanism in this paper successfully solves the multicast routing problems. When the topology of Ad Hoc networks is change infrequently, the method which not only optimizes the routing tree with guarantee the bandwidth and end-to-end delay, but also controls the complexity of the algorithm effectively, is suitable for large scale of Ad-hoc networks.
