MT3-DA: Multicast Optimization Mechanism Based on Transmission Time and Interference Minimization in Wireless Mesh Networks
Multicast support is critical and a desirable feature of multi-radio wireless mesh networks. However, the nature of wireless network, i.e. broadcasting and interference, makes it a challenge to efficiently support multicast services. In this paper, we study how to build a multicast structure with maximum average throughput in terms of minimum transmission time and channel interference in a multi-radio wireless mesh network. The proposed MT3-DA mechanism takes both route setup and channel assignment into account. It first builds the multicast tree based on minimum transmission time between neighboring routers, and then uses destination-aware channel assignment strategy to minimize interference through assigning low-interference overlapping channel to the router that holds more descendant destinations. Simulation results show that the proposed MT3-DA can construct the multicast trees which have higher throughput than that of 2-MCM and M4 in multi-radio wireless mesh networks.
