摘　　要：针对AdHoc网络中带QoS约束的多播路由问题,提出了一种新的结合MAODV多播路由发现方法和粒子群优化算法的QoS多播路由发现算法。仿真试验显示该算法较好地改进了端到端传输的代价、延时和带宽利用率,能够找到一棵消耗趋于最小、状态稳定的多播路由树。Focusing on the multicast routing problem with multiple QoS constraints of Ad Hoc networks, a new QoS route discovery algorithm based on MAODV multicast routing discovery method and particle swarm optimization algorithm. Simulation results show that, with the proposed QoS multicast routing algorithm, end-to-end cost, delay and bandwidth on a route can be improved in most of cases. Using this method, a group broadcast tree at the near lowest cost and most stable state can be found.
