In this paper, we investigate a disaster management system using D2D cooperative communications. Specifically, we consider two D2D cells, one is in healthy area and the other is in disaster area, where a user equipment (UE) in healthy area aims to assist a UE in the disaster area to recover wireless information transfer (WIT) via an energy harvesting (EH) relay. In the healthy area, a cellular base...
In this paper, we consider a secure wireless powered device-to-device (D2D) communication in the presence of the multiple eavesdroppers, where a smart hybrid base station (BS) in cellular network not only charges for the D2D transmitter to guarantee power efficiency for the D2D network, but also serves as a cooperative jammer (CJ) to interfere with the eavesdroppers. Although the cellular networks...
