Energy-Efficient D2D Discovery for Energy-Harvesting Proximal IoT Devices

Performance Analysis in Wireless Powered D2d- Aided Non-Orthogonal Multiple Access Networks

“…However, they strictly require more power to remain its operation and in order to prolong UEs battery lives, and offload dense traffic of BSs the literature introduced the self-powered architecture socalled energy harvesting (EH). As in [1]- [8], the works have lately adopted some transmission policies for EH cooperative networks. EH relays were first implemented in cooperative communication [1].…”

“…In-depth simulations are accompanied to calculate the outage and throughput performance under various system parameter configurations. Thus, under general energy harvesting profiles, the authors in [5]- [8] proposed a number of transmission policies. Particularly, because the stationarity of the harvested process, idea of combining relay choice and power division schemes are specified in [5].…”

“…Likewise, in [6], [7], since during any time of data transmission, energy can be scavenged, several power allocation schemes for cooperative EH networks were put forward. The study in [8] investigated the constraints of an LTE-A system to serve energy-harvesting D2D devices and developed a low complexity procedure for D2D discovery resource allocation. The main advantage of D2D communication is a hopeful perception used to expand user experience and improve resource utilization in cellular networks, enabling two close-by D2D devices to create a direct local link and without consideration on helping base station.…”
