Abstract: Based on the dynamic characteristics of overlay multicast nodes, this paper studies the problem of degree and delay constrained on the self-organizing 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.
