Impact of stochastic RF energy harvesting relay on wireless point-to-point network

Abstract

In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of this stochastic energy harvesting model (SEHM) are discussed and the performance of a point-to-point (P2P) wireless link is evaluated in the presence of such an EH model and decode-and-forward (DF) relaying in terms of average error and outage probabilities. The performance limitations and practical applicability of the SEHM compared to the DF scenario in multi-relay case are studied. The simulation results show the performance improvement of this EH cooperative relaying compared to the traditional relay-based cooperative communications. 2016 IEEE.
