Bandwidth-satisfied multi-path multicast routing in wireless mesh network
Xu-Zhen · International Conference on Computational Problem-Solving · 2010
Wireless mesh network has recently emerged as a promising technology for next-generation wireless network. Many important applications, such as audio/video conferencing, require multicast communication with quality-of-service (QoS) guarantee. In this paper, QoS multicast routing in wireless mesh networks are investigated. The paper studies TDMA-based timeslot allocation, and presents an effective algorithm for calculating bandwidth of a multicast tree. The paper also proposes a multi-path multicasting routing algorithm, and two strategies for constructing multiple trees are studied. Simulation results show that compared with MAODV, multi-path multicasting routing algorithm can improve the performance of multicast routing in terms of success ratio and network cost.
