Large deployment of IEEE 802.11 wirelesses LANs (WLANs) is perceivable in the present world. In order to reduce interference in the spectrum, the 802.11 standard specifies the use of several orthogonal channels. It is established that the static channel assignments are inadequate to handle the traffic variations effectively, besides some of the channels being underutilized in these types of networks. So, the authors need to employ a dynamic channel allocation algorithm, to determine the optimal channel to be used at any given time and place. If a channel allocation scheme does not consider the other sensitive network issues such as bandwidth allocation, power available at the node etc., it may increase medium access contention and co-channel interference, adversely affecting the aggregate capacity of the network.
