Cognitive radio (CR) technology allows the observation of the network conditions to dynamically discover available and underutilized spectrum. A cognitive network is the framework that uses the CR to take advantage of underutilized spectrum. The availability of using multiple interfaces and channels with cognitive radio abilities in wireless devices is expected to alleviate the capacity limitations that exist in traditional single channel wireless mesh networks.CoSAP has knowledge of its three hop neighbors SOP so that it can create the conflict graph for channel assignment. ... In this example every nodes initial SOP is 1, 2, 3 and each access point can randomly chose a channel between 1, 2, and anbsp;...
