A New Protocol based on Optimal Capacity for Energy Harvesting Amplify-and-Forward Relaying Networks

Popis výsledku v původním jazyce

In this paper, we present a new proposed protocol for radio frequency (RF) energy harvesting (EH) amplify-and-forward (AF) relaying networks. Specifically, a source communicates with a destination via the assistance of multiple energy-constrained relays over Nakagami-m fading channels by using the AF scheme. The hybrid RF EH architecture, i.e., time switching (TS) and power splitting (PS), is deployed at the relays in combining manner to power the relays in which the power splitting ratio is dynamically adjusted according to the variation of channel coefficient to achieve the optimal capacity. A novel protocol for this considered system, namely TSAPS-ORS, is proposed based on time switching - adaptive power splitting (TSAPS) architecture and optimal relay selection (ORS) scheme. Furthermore, the Monte-Carlo computer simulation is also provided to validate the effectiveness of our proposed protocol. Finally, in order to understand the behavior of this system, we evaluate the performance in terms of outage probabilty in various system key parameters, such as transmit signal-to-noise ratio (SNR), energy harvesting time, relay location, and number of relays.
