ABSTRACT
In an environment where a prospective listener could hear the PT’s sensitive information, a Primary transmitter (PT) will communicate sensitive medical data. This paper addresses the problem of secured transfer of information for the Internet of Medical Things (IoMT) based on cognitive radio with wireless energy scavenging. By making use of spectrum sharing, the ST also sends its own data at the same time. A unique method for determining the ideal characteristics, namely better secrecy transmission rate and energy efficiency, is put forth. For improving energy efficiency, the squirrel search algorithm and social spider algorithm were jointly used. The secrecy is improved by using karatsuba encryption technique. The CVX tools can be used to quickly obtain the energy efficiency and secrecy rate. When compared to optimal secure beamforming, simulation results show that the suggested protocol under consideration can successfully increase the prime secrecy transmission rate while maintaining the secondary system’s transmission rate.
