Throughput Maximization for Two-Way Buffer-Aided and Energy-Harvesting Enabled Multi-Relay Networks

Abstract: For years, relay communications have been witnessed to extend the network coverage and improve the throughput and reliability of wireless systems. In this paper, we focus on throughput maximization for the two-way buffer-aided relay network with finite data buffers and limited energy battery, wherein relays have no fixed power supply and they replenish energy from the Radio Frequency (RF) signal radiated by source nodes. Specifically, by jointing the time switching and energy splitting for RF energy harvesting… Show more

“…We obtain 6, 4, 2, and 1 for the diversity order value from lowest toward highest outage curves. These confirm our derivation in (52). Figure 11 illustrates the delay-sensitive throughput of scenario II in (41) against τ for the various values of average transmit SNR.…”

“…The works in [41, 42] are also based on two‐way EH networks. The study in [41] presents a BA AT framework, where two users are exchanging messages with the help of a relay, with very large buffer size and energy storage size, by going through the three stages: EH, multiple‐access, and broadcast transmission.…”

“…In this DAAT scheme, a fundamental trade‐off exists between the average transmission rate and the average delay, where queue stability and the maximum achievable rate region can be reached by tolerating a particular time delay [41]. With regard to [42], a throughput maximisation is considered for the two‐way BA and EH‐enabled multi‐relay network with finite buffers, and limited energy battery in the absence of a direct S–D link. Combining time switching and energy splitting for RF EH, a three‐time sub‐slot transmission model is designed, balancing the energy storage and consumption, where the three phases in a slot are: EH, information access and broadcast transmission.…”

“…In [7], by taking both the quality of the links and the energy stored in the RNs into consideration, the benefits of relay selection on multiple EH based buffer-aided relay nodes (RNs) was investigated. In [8], the achievable throughput of a buffer-aided two-way relaying system with EH were derived.…”
