A SWIPT based device to device cooperative network,"

This paper proposes a simultaneous wireless information and power transfer (SWIPT)-based cooperative device-to-device (D2D) network, where the D2D pairs are distributed in a circular area. Such networks are particularly helpful in public safety scenarios, where battery constraints signify the need for a resource efficient communication protocol. The node distribution in the circular area is modeled through a homogeneous Poisson point process (PPP), where a central node is responsible for intra-region signaling. Expressions for the ergodic rates of single-hop and dual-hop scenarios are derived, assuming a Rayleigh fading channel with path loss. A transmission flow mechanism encompassing energy harvesting and decode-and-forward nodes is devised for end-to-end transmission. Performance analysis of the proposed technique reveals the impact of different network parameters on the magnitude of energy harvested and outage capacity.
