Cooperative spectrum sensing in wireless sensor networks using forager bee’s intelligence

Abstract

Increasing utilization of wireless sensor networks Leads scarcity problems in spectrum allocation channels. The development of cognitive radio networks over wireless spectrum technology based on both licensed and unlicensed user. The maximum interference of users are mitigated to use unlicensed bandwidth. Due the high interference of bandwidth sharing enormously by secondary users (SUs). To sense the unlicensed user on over problematic condition remains the overhead problems on cognitive radio networks. In this paper, Co-operative spectrum sensing as well as spectrum allocation with Forager Bee’s Intelligence algorithm is used. The idle spectrum band in licensed band is identified and allocated to sensor nodes, which reduces the interference and collisions in WSN and avoids packet retransmission. This ensures fair energy in WSNs and Spectrum resources are utilized efficiently.
