A Yet Efficient Path Selection in Cognitive Radio Network

Cognitive radio (CR) is a type of wireless communication in which wireless devices use environmental sensing to detect and change transmission parameters. In this paper, we propose the Probabilistic and Deterministic Path Detection (PDPS) Protocol for cognitive radio networks. PDPS aims to increase the probability of finding the path of best quality between any source and any destination. The performance of the proposed protocol is evaluated by conducting comprehensive simulation scenarios and experiments using a special simulator which was built using Java. The simulation results highlight the benefits of the proposed path selection technique in comparison to one of the state-of-art protocols.
