Abstract :
In this paper, we discuss the framework of cognitive radio network, analysis motivations for cross-layer design and security in cognitive radio network (CRN) first. Secondly, we proposed a novel architecture in which the dynamic channel access is achieved by a cross-layer design between the PHY and MAC layers for cognitive radio network. Moreover the resolution of cross-layer security problem is proposed and analysis in mathematic. Finally, we discuss the security issues of spectrum sensing for Centralized CRN and a novel centralized dynamic channel access mechanism is proposed, simulation shows it can improve network performance.
