摘　　要：随着多媒体业务的普及,如何为MANET多播路由提供QoS保障成为研究热点。提出了一种带宽和时延受限的QoS多播路由协议,它利用遗传算法搜索满足QoS要求的最优多播树。仿真结果表明该协议收敛速度快,寻径成功率高,它为移动网络中具有QoS保障的多播通信提供了一种有效途径。With the rapid popularization of multimedia service,how to guarantee QoS of muhicast routing for MANET has become hot issue.A QoS multicast routing protocol with bandwidth and delay constraint was proposed in this paper.It utilizes genetic algorithm to search optimized muhieast tree which satisfies the QoS request.The simulation results show that the protocol has fast convergence and high routing searching ratio.It provides an available approach for multicast communication with QoS guarantee in mobile networks.
