“…Full-duplex relaying (FDR) [33][34][35][36][37] and successive relaying (SR) [38][39][40][41][42][43][44][45][46][47][48][49][50][51] are two representative techniques to further improve the spectral efficiency. Since sophisticated fullduplex circuits and self-interference suppression technology are no longer needed, SR provides us with an effective solution that simultaneously selects two relays to receive information from the source and forward the message to the destination, such that it can be interpreted as a virtual FDR.…”

“…The aforementioned research works aim to either analyze or optimize the achieved performance and do not attempt to exploit the great benefit of the bufferaided communication strategy. For a buffer-aided successive relaying network, the transmission policy design and resource scheduling were studied in [44][45][46][47][48][49] without energy harvesting. In [50], the relays of an EH-based SR network were provisioned with data buffers and energy storages, and the network throughput was maximized in the absence of inter-relay-interference (IRI).…”

“…Nonetheless, the data buffer at the relay was not exploited. In [44][45][46][47][48][49], the achieved performance and resource management for a buffer-aided SR network were investigated without considering energy harvesting capability. Under the complete interference cancellation assumption, the throughput maximization problem of an EH-based SR network without inter-relay-interference (IRI) was studied in [50] by considering both the data buffer and energy storage at relay.…”

In this paper, we consider a wireless powered cooperative network, where two energy-constrained buffer-aided relays harvest energy from the source to assist the information delivery to the destination. To improve the spectral efficiency, a wireless powered successive relaying (WPSR) protocol is proposed to allow both relays to receive the information from the source and forward the buffered data to the destination, taking into consideration of the inter-relay-interference (IRI). We first reveal the impact of data buffers and energy storages at the relays by the achievable throughput comparison of the WPSR scheduling schemes with and without considering data buffers and energy storages. Our analysis validates the great potential of the buffer-and-forward data transmission and the harvest-store-use energy management strategies. Then, the network throughput is maximized via adaptive time and power allocation subject to the stability constraints of data buffers and energy buffers, and an adaptive wireless powered buffer-aided successive relaying (WPBSR) scheduling scheme is proposed. The proposed scheme approaches the optimal throughput of the wireless powered successive relaying network with bounded delay and finite length of data and energy buffers. Numerical results validate the analysis and noticeable spectral efficiency gain.

“…In [38,39], the IRI effects specific to VFD were taken into consideration, allowing IRI to be canceled by multiple antenna processing at relay nodes. Additionally, the VFD scheme for multi-hop networks was investigated in [40]. Moreover, the algorithm of a low-latency for the successive opportunistic relaying (LoLA4SOR) was proposed in [41], which is capable of operating in both HD and VFD transmissions while maintaining the high diversity level and the low packet delay.…”

This paper proposes a buffer-aided relay selection that is capable of exploiting both half-duplex and virtual full-duplex (VFD) transmissions in a hybrid manner. In the proposed scheme, we consider a two-hop cooperative network where each node is equipped with a single antenna, and no direct link between the source to the destination exists. The proposed scheme consists of five relay selection modes: two unicast modes, a broadcast mode, a cooperative beamforming mode, and a VFD mode. Owing to the broadcast mode, multiple relay nodes can seamlessly have a common packet; this mode is capable of solving the inter-relay interference problem imposed on the VFD mode. The proposed scheme's theoretical performance bounds on the throughput, the outage probability, and the delay are derived. It is demonstrated in our simulations that the proposed scheme attains higher performance in terms of a throughput and an outage probability than the conventional schemes while maintaining an acceptable average end-to-end delay profile.
