Outage performance evaluation of device-to-device system with energy harvesting relay

Abstract

The development of Internet of Things (IoT) devices as well as the increase of nodes in wireless networks, motivates the use of node?s cooperation for wireless system performance improvement. On the other hand, the power requirements of the increasing number of nodes leads to the need for new powering sources. In this paper we consider device-to-device (D2D) relay-assisted system, where decode-and-forward (DF) relay is not equipped with its own power supply, but it harvests energy and uses it for the data transfer to the destination node. System performance is derived for the Fisher-Snedecor F composite fading channel model and energy harvesting protocol based on time-switching scheme. The closed-form approximate expression for the outage probability is derived, that corresponds to the exact results. The impact of the channel fading and shadowing parameters and time-switching factor of energy harvesting protocol on the system performances are investigated. Numerical results are confirmed by an independent simulation method.

Outage Analysis of Unmanned-Aerial-Vehicle-Assisted Simultaneous Wireless Information and Power Transfer System for Industrial Emergency Applications

“…In most scenarios, information is transferred among communication nodes over wireless channels. The outage performance analysis of dual-hop relaying systems with ground relays used for both information signal retransmission and RF energy harvesting can be found in [ 34 , 35 , 36 , 37 , 38 ], for Nakagami- m and Fisher–Snedecor fading environments. In our work, we extend the number of communication nodes in accordance with the specific application for industrial purposes.…”
