In this paper, we propose an energy-harvesting based decode-and-forward multi-hop cognitive relay protocol, where secondary users harvest energy from the radio frequency signals transmitted by multiple dedicated power beacons (PBs) to support the information transmission. The secondary transmitters including source and relays must adjust their transmit power to satisfy interference power constraints...
In this paper, we consider an incremental cooperative relaying network (IR-CRN), where a relay node harvests the radio energy from the source signal using the time-switching mechanism. Specif cally, we propose a scheme named as IR-CRN which enhances spatial diversity gain by utilizing the incremental relaying protocol. The destination node of the IR-CRN scheme employs maximal ratio combining (MRC)...
In this paper, we propose an energy harvestingbased jamming scheme to enhance secrecy outage probability (SOP) for cooperative relaying protocols. In the proposed scheme, one of available relays is selected to forward data from a source to a destination, while an energy-constrained relay harvests energy from the source’s radio frequency signals to generate artificial noise to an eavesdropper. Moreover,...
