- In Cognitive Radio (CR) systems, the spectrum handoff is a key-factor as it could affect propagation path nature. Accordingly, it may affect the overall system coverage and performance. In this article, a new spectrum-handoff strategy is proposed in order to minimize the occurrence of spectrum handoff and hence to achieve a better transmission performance. Specifically, it provide a better channel-selection strategy combined with a power adaptation scheme. This is to reduce/avoid interference and also to conserve power consumption in the system and hence get a greener communication system. The simulation results show an enhancement of up to 64%in switching requests. Also, the system is analyzed in terms of BER and compared to others to show the performance maintained.
