A new channel assignment strategy towards the wireless mesh networks

Recently, the wireless mesh network attracts the interest of many people as a new broadband network of the next generation. The wireless mesh network consists of terminals only, then a terminal in the network can communicate with the other terminal beyond the transmission range by multihopping in the same way as in the ad hoc networks. In this network, a communication link between two terminals which can communicate directly is required a channel. Since cochannel interference may occur, we need to assign channels to communication links carefully. In this paper, we describe a channel assignment strategy which takes the degree of cochannel interference into consideration, and we also evaluate the effectiveness of this strategy by computer simulations. We show that this strategy is more effective than the strategy which does not take the degree of cochannel interference into consideration.
