This paper explores the advantages of employing a selective relay selection method compared to a random relay selection approach in millimeter-wave (mmWave) networks assisted by amplify-and-forward (AF) relays, featuring two source-destination pairs and two relays. The investigation includes an analysis of the outage probability associated with the end-to-end signal-to-noise ratio (SNR) for users under both relay selection strategies in a log-normal shadowing channel. The proposed relay selection technique has been incorporated into relay-assisted mmWave networks, considering the shadowing effects caused by blockages. Simulation results demonstrate that the selective relay assignment outperforms random relay selection.

摘要

This paper explores the advantages of employing a selective relay selection method compared to a random relay selection approach in millimeter-wave (mmWave) networks assisted by amplify-and-forward (AF) relays, featuring two source-destination pairs and two relays. The investigation includes an analysis of the outage probability associated with the end-to-end signal-to-noise ratio (SNR) for users under both relay selection strategies in a log-normal shadowing channel. The proposed relay selection technique has been incorporated into relay-assisted mmWave networks, considering the shadowing effects caused by blockages. Simulation results demonstrate that the selective relay assignment outperforms random relay selection.
