Abstract	Cognitive radios (CR) provides a promising solution to the problem of spectrum scarcity by increasing spectrum efficiency. CR coexists with the licensed users in a network. The network is assumed to be ad-hoc in nature where the master/controller of this ad-hoc network coordinates for spectrum allocation with the surrounding CR. In this paper, a two level hierarchical fuzzy system for adaptive bandwidth allocation is designed where one system evaluates the access latency based on an analytical model and the second system allocates the bandwidth to SU on the basis of priorities assigned to different traffic types of SU.
