ABSTRACT
Cognitive radio (CR) technology is accepted as the most efficient method to improve the spectrum efficiency, which utilizes the available spectrum opportunistically in wireless communication networks. CR acts as a secondary (unlicensed) user to access the primary (licensed) user frequency bands when they are not being used, and release the frequency bands when the primary users are detected. In this paper we propose the system for efficient and flexible spectrum access and utilization amongst the secondary users. The proposed system is implemented by developing fast and efficient algorithm using CR concept. The experimental results have addressed the issues discussed in the proposed system. We optimized the switch delay between the nodes and improved the packet transmission amongst the nodes.
