Cognitive radio (CR) is a promising technology to overcome the challenge of additional spectrum requirement posed by internet of things (IoT) supported applications. This paper brings out the comparative performance analysis of different optimization techniques for adapting the transmission parameters in five distinct transmission scenarios for a multicarrier based CR-IoT network. Parameter adaptation problem is rather complex to be solved for a multicarrier system with large number of transmission variables. Inspired by the efficient exploration and exploitation abilities of recently proposed nature inspired meta-heuristic optimization algorithms, the application of these techniques has been investigated for solving the proposed multiobjective optimization problem.
