Power allocation in cognitive radio networks using genetic algorithm

Abstract

Cognitive radio is one of the Frontline areas in wireless communication. With the evolution of 5th generation wireless communication techniques, the expected use of cognitive-communication will be enhanced. The joint model consisting of the Overlay and Underlay spectrum mechanism has been considered for transmission rate optimization using the genetic algorithm and the performance improvement has been recorded over the suboptimum scheme using the JOUSAM model for the cognitive radio network.For a given power budget and interference limit, the transmission rate is optimized with respect to power and bandwidth.
