Full-Duplex Cooperative Relaying with Non-Linear Energy Harvesting for Vehicular Communication.

This paper analyses the performance of full- duplex (FD) dual-hop vehicular cooperative network with decode-and-forward (DF) protocol. At FD relay nodes, we examine the effects of non-linear hybrid power time splitting (PTS) based energy harvesting (EH). All three nodes—source (S), relay (R), and destination (D)—are assumed to be moving vehicles. The expressions for the system’s outage probability (OP) over double (cascaded) Rayleigh fading channels are derived. We also analyse the impact of residual self-interference (RSI) caused at FD relay on system’s performance. We compare the performance of system with two relay selection techniques, namely, maximum channel gain-based (Max-G) relay selection and minimum RSI-based (Min-SI) relay selection. This paper considers the joint effect of time splitting ratio and self-interference cancellation (SIC) level to find the optimum EH duration. Additionally, the effect of time splitting ratio and average signal-to-noise ratio (SNR) on outage and throughput performance of the system are also investigated in this paper. The derived expressions are validated through Monte Carlo simulations.
