Adaptive Energy Harvesting Relaying Protocol for Two‐Way Half‐Duplex System Network over Rician Fading Channels

Abstract

We investigate the system performance of a two-way amplify-and-forward (AF) energy harvesting relay network over the Rician fading environment. For details, the delay-limited (DL) and delay-tolerant (DT) transmission modes are proposed and investigated when both energy and information are transferred between the source node and the destination node via a relay node. In the first stage, the analytical expressions of the achievable throughput, ergodic capacity, the outage probability, and symbol error ratio (SER) were proposed, analyzed, and demonstrated. After that, the closed-form expressions for the system performance are studied in connection with all system parameters. Moreover, the analytical results are also demonstrated by Monte Carlo simulation in comparison with the closed-form expressions. Finally, the research results show that the analytical and the simulation results agree well with each other in all system parameters.

Exploiting Direct Link in Two-Way Half-Duplex Sensor Network over Block Rayleigh Fading Channel: Upper Bound Ergodic Capacity and Exact SER Analysis

“…In the second interval time T/3, the R harvests energy ρP2 from the source node S2, and the source S2 uses the energy (1−ρ)P2 for information transmission to R and S1. Finally, the remaining time slot T/3 is used for information transferring from the R to the source nodes S1 and S2 [30][31][32][33][34][35].
