A Novel Channel Assignment Scheme for Multi-channel Wireless Mesh Networks

An important issue of multi-channel multi-radio wireless mesh network (MRMC-WMN) is how to assign multiple available channels to the radios in order to minimize the wireless communication interference and maximize the network throughput. In this work, we study the problem of channel assignment in MRMC-WMN, and the optimization problem is known to be NP-complete. We propose a novel dynamic channel assignment scheme which can be performed in distributed manner. Moreover, our scheme is suitable for both unicast and multicast communication. The analysis and comparison demonstrates that our proposed scheme is feasible and more efficient compared with the existing distributed channel assignment schemes.
