Title

Channel assignment with user coverage priority and interference optimization for multicast routing in wireless mesh networks

Abstract

In order to improve multicast performance in wireless mesh networks, we consider both multicast tree construction and channel assignment in this paper. To maximize the possibility of providing good service to the users, we treat the user coverage of each destination as the top priority in channel assignment. In addition, we propose the multicast tree constructing algorithm (namely CIOMT) and channel assignment algorithm with the name CIOCA. In the CIOMT algorithm, each destination selects the minimum interference path to the constructing tree and joins into the constructing tree. For QoS consideration, the source-todestination hop count is up bounded. In the CIOCA algorithm, the nodes are assigned the sending channels by the descending order of priority. During the channel assignment process, the channel with minimum interference to the whole tree will be selected and assigned to the corresponding interfaces. Simulation results have shown that the proposed solution outperforms the other existing algorithms.
