    Performance Evaluation for Relay Selection on Device-to-Device (D2D) Communications in Rayleigh Fading
    (2021 3rd International Conference on Advancements in Computing (ICAC), SLIIT, 2021-12-09) Woo, W.H.; Annur, R.; Ponnusamy, V.
    Relay-aided device-to-device (D2D) is an alternative method to support short-distance direct communication in the facts of poor channel links and limited coverage. In a wireless communication system, failed communication can be caused by many factors, such as a lack of energy to maintain the transmission or the inability to hear the signals due to weak RSS. This paper presents Received Signal Strength (RSS) and battery awareness as the parameters of relay selection to select one or more optimal relays. In order to study the impact of radio propagation on the proposed scheme, the D2D network is implemented in the Rayleigh fading with obstacles environment. Performance is determined by packet drop, throughput, and end-to-end delay. Overall, the proposed scheme performs better than the existing scheme. From the evaluations, the packet drop in the proposed scheme is lesser than the existing scheme, reducing the throughput by 46%. The end-to-end delay in the proposed scheme is lesser than the existing scheme by 0.003s.
