Performance of Energy Harvesting Aided Multi-hop Mobile Relay Networks With and Without Using Cooperative Communication

Abstract

This paper studies performance of two radio frequency (RF) energy harvesting (EH) aided multi-hop mobile relaying models. In the first one, named MHM2M-DT, a mobile source attempts to send its data to a mobile destination with help of intermediate mobile relays. In MHM2M-DT, the data transmission at each hop is direct transmission. In the second one, named MHM2M-CC, cooperative communication is used at each hop to obtain higher spatial diversity. All the transmitters in our schemes have to harvest the RF energy from a power station, and use this energy to transmit the source data. We evaluate performance of MHM2M-DT and MHM2M-CC over double Rayleigh fading channels, in terms of end-to-end (e2e) outage probability (OP) and throughput (TP). Finally, Monte Carlo simulations are realized to validate the analysis as well as to compare the OP and TP performance of MHM2M-DT and MHM2M-CC.
