Abstract

Cognitive Radio Sensor Networks (CRSNs) are resource-constrained networks that require dynamic mechanisms for data transfer. The dynamic nature of CRSN demands dynamic time slots be allocated for node communication. The Licensed users predominantly occupy the spectrum which makes unlicensed users be deprived of accessing the channel. Allocating underutilized portions of the spectrum to unlicensed users must be dynamic. In this work, Dynamic Slots Computation (DSC) based on delay and traffic parameters is implemented for dynamic spectrum allocation for unlicensed users in CRSN. Based on network parameters, a legitimate channel, possessing good quality is selected. Simulation results show that DSC algorithm significantly improves the energy efficiency, packet delivery ratio, and throughput of CRSN in comparison with other existing CRSN protocols.
