An important issue of multi‐channel multi‐radio wireless mesh network 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 is based on network coding (NC) and data flow. Our scheme can be performed in distributed manner and is suitable for both unicast and multicast communication. Compared with the basic dynamic CA scheme, the analysis and comparison demonstrates that our proposed scheme has less communication cost and less interference.
