Keywordsaccess protocols, adaptive radio access technologies, adaptive wireless access system design, admission control design, advanced transceiver, cognitive physical layer, cognitive radio, cognitive radio networks, cross layer design, efficient spectrum allocation, MAC optimization, medium access control layer, radio access networks, radio interface designs, spectral utilization, spectrum sensing, telecommunication congestion control, transceivers, utilization algorithms

In this talk, an overview of enormous potential of improving spectral utilization by using cognitive radio is presented. The current main focus on cognitive radio design is to research and develop adaptive radio access technologies, that have lead to many challenges in physical layer, medium access control (MAC) layer and cross layer design. Moreover in the talk, research scopes and challenges that have come up in several layers are presented. Specifically, the following research issues are discussed: spectrum sensing, efficient spectrum allocation and utilization algorithms, advanced transceiver and radio interface designs for the cognitive physical layer, MAC optimization, admission control design, and enabling security mechanism
