Abstract

Abstract : This study investigates the performance of practical wireless exclusive OR (XOR) two‐way relay (TWR) system, in which finite buffer, lossy wireless channels and non‐negligible signalling overhead are considered. Specifically, the authors develop a new analytical model to explicitly characterise the transmissions of both the end‐nodes and the relay. The impact of scheduling on the throughput, queuing delay, power consumption and buffer overflow probability of XOR‐TWR is evaluated. Validated by simulations, the model can precisely quantify the performance of XOR‐TWR and adequately allocate the relay's buffer adapting to the wireless link qualities and signalling overhead.
