摘　　要：针对覆盖组播节点的动态特性,研究自组织覆盖网络带度和延时约束的组播动态路由问题,提出了动态覆盖组播路由算法AHMQ。组播树由目的节点驱动动态渐近形成,动态路由优化在通信过程中进行。协议是软状态的,仅要求节点维护局部状态信息,同时利用覆盖网络技术和无线媒质的广播能力,降低了网络负载,提高了重构能力。对算法进行了分析研究,通过实验验证了该算法具有较好的性能。Based on the dynamic characteristics of overlay multicast nodes, this paper studies the problem of degree and delay constrained on the selforganizing overlay network multicasting dynamic routing , and proposes a new dynamic overlay multicasting routing algorithm AHMQ. Multicast tree is asymptotically formed by the destination node drive, and optimization for dynamic routing is made in the communication process. Protocol is in a soft state, and it only requires a node to maintain local state information. At the same time, by using the overlay network technology and wireless media broadcast capability, the network load is reduced and the reconstruction ability is improved as well. By analyzing the optimization algorithm, experimental results show that this algorithm has better performance.
