摘　　要：随着移动AdHoc网络的应用不断扩大,研究其具有QoS约束的多播路由技术已成为网络及分布式系统领域的一个重要研究课题。论文基于作者设计的分层结构多播路由算法MALS,提出了以权重因子方法进行分簇处理的QoS多播路由算法MALS_QoS。和MALS相比,MALS_QoS算法具有QoS的约束功能,能产生具有带宽、剩余能量、延时和延时抖动等约束的QoS多播树。仿真实验表明,MALS_QoS能满足QoS约束的多播要求,具有较好的性能。With the rapidly expanding application of Ad Hoe networks,QoS muhicast routing with multiple QoS constraints in Ad Hoc networks has become a very important research issue in the area of networks and distributed system.According to routing algorithm of layered structure MAIS designed by author,multicast routing algorithm with multiple QoS constraints for Ad Hoc networks MAIS_QoS is proposed in this paper,which forms clusters through weight factor method.Compared with MAIS,MAI_S_QoS has a function of QoS control and it can produce a multicast routing tree with multiple QoS constraints of the bandwidth,remainder energy,delay and delay jitter.Simulation results show that MAIS_QoS can meet multicast requirement with multiple QoS constraints and has a good performance.
