Research on the channel assignment problem for multicast in multi-channel multi-radio wireless mesh networks

Wireless mesh network (WMN) that provides high quality of service to end users has become a kind of emerging access pattern for wireless network. Researching on multi-channel multi-radio (MCMR) wireless mesh network has become more and more at present. Channel assignment problem is extremely important based on the limit of usage channel, so it is hugely important for the channel assignment. In our paper, we first make a brief introduction to the idea about Multi-Channel Multicast (MCM) algorithm, and point out its potential shortcomings. To improve these shortcomings, another algorithm based on quality of link in Multi-Channel Multicast and another channel assignment based on link interference aware are presented in our paper, in addition, improve the network throughput compared with MCM algorithm.
