Performance evaluation of cooperative relay networks with one full-energy relay and one energy harvesting relay

Abstract

In this paper, we propose a cooperative relay protocol in which the data transmission between a source and a destination is performed via the assistance of one full-energy (FE) relay and one energy harvesting (EH) relay. In addition, the EH relay harvests energy from the radio frequency (RF) signals of the source and the FE relay, follows a time switching method. For performance evaluation, we derive exact and asymptotic expressions of outage probability (OP) for the proposed protocol over Rayleigh fading channels. Then, the analytical results are validated by computer simulations using Monte Carlo method.
