HAND-OFF STRATEGY INCOGNITIVE RADIO NETWORKS

Abstract:
This paper presents an intelligent mobility criteria for Cognitive radio (CR) technology. CR technology is a promising solution to enhance the spectrum utilization by enabling unlicensed users (Secondary User SU) to exploit the spectrum in an opportunistic manner. Since unlicensed users are considered as temporary visitors to the licensed spectrum, they are required to vacate the spectrum when a licensed user reclaims it. Due to the randomness of the appearance of licensed users (Primary User PU), disruptions to both licensed and unlicensed communications are often difficult to prevent, which may lead to low throughput of both licensed and unlicensed communications. When the SU moves out of coverage of PU, then communication is impossible. Here I proposed a method to sense the nearest available PU and hence communicating over the spectrum with minimum delay and no throughput loss.
