Recently, tremendous utilization of wireless networks has led to sever scarcity of radio spectrum resources. TV White Spaces (TVWSs) as novel bands enabling Cognitive Radio (CR) technology to improve spectrum resources utilization, have attracted significant standardisation efforts such as IEEE 802.11af, IEEE 802.16h and 802.22. As these heterogeneous networks may operate on the same channels of TVWSs,...
Cognitive Radio is a promised solution to conquer the inefficiency utilization of spectrum resources, which is induced by the traditional fixed spectrum allocation scheme. In cognitive wireless networks, deficient matching between users' demands and spectrum resource may cause communication deterioration while superfluous matching may cause spectrum inefficient utilization. In this context, by considering...
