Cognitive Radio Networks

The explosive growth in wireless services over the past several years illustrates the huge demand for spectrum-based communications. Advances in technology continue to tax the finite resources of the available spectrum. Cognitive Radio Network (CRN) is an efficient communication paradigm which allows unlicensed users access to licensed bands without interfering with existing users. This book covers a range of cognitive radio network issues. It addresses the physical layer, medium access control, the routing layer, cross-layer considerations and advanced topics in cognitive radio networks. Research, management, and support are addressed, as are cognitive techniques such as position and network awareness, infrastructure and physical and link layer concerns.
