Abstract: Nowadays due to easily available hardware and availability of unlicensed frequency spectrum the use of WLANS has increased tremendously. Such WLANS are set up by untrained system administrators with no topology planning. The Access Points are also placed haphazardly. The performance of such Uncoordinated WLANs is greatly affected due to availability of limited number of non-overlapping channels. The cognitive radio provides the clients to make use of free channels from licensed spectrum when they are not in use by primary users. Thus in cognitive environment more channels are available to the clients. This paper describes a novel channel assignment scheme for cognitive radios.
