Cognitive Radio-Based IoMT with Wireless Energy Harvesting for Secure Transmissions

Abstract

The challenge of safe transmission of the collection of wireless energy to the cognitive Internet of Medical Things (IoMT). The primary-transmitter (PT) can listen to PT sensitive information, if we consider the potential eavesdropper and transmit sensitive medical information through a multi-antenna secondary transmitter to the secondary Transmitter (ST). The ST also sends its personaldata simultaneously through spectrum sharing. The energy-restricted cooperativescheme will be equated to the cooperative scheme without energy restrictions and the non-cooperative energy-restricted system in this studying. The energy Harvesting (EH) ratio and secures beamforming are proposed as branch-reduceand-bound (BRB). Furthermore, the conditions are specified for the system to switch from cooperative to non-cooperative modes. To make simpler research, a dominant system method is used to achieve a closed communication in the scheme's stable throughput field. Also note that, compared with the conventional system, the proposed system model protocol considered will encourage the primary secrecy transmission rate and guarantee the transmission rate of the subordinatescheme.
