Abstract

A scalable and efficient hybrid application-layer multicast protocol-DHMT (Dynamic Hybrid Multicast Tree) is proposed in this paper. It adopts the hybrid architecture of hierarchy and Fibonacci tree to multicast packets efficiently. In DHMT, the underlying topology characteristic is considered by introducing an idea of local area to reduce packet delivering on costly links. In each local area, members are constructed into a hierarchical architecture in term of layer and cluster. The roots of all local hierarchical architecture are organized into a Fibonacci multicast tree. In addition, the cores in DHMT are selected dynamically to reflect the instantaneous network situation. The architecture characters improve the delay performance of DHMT. The simulation shows that DHMT is scalable and efficient and it works well especially for large multicast group.
