Published in 2022 at "IEEE Access"

DOI: 10.1109/access.2022.3151168

Abstract: This paper studies an energy-efficient beamforming and resource allocation for multi-access edge computing (MEC) systems consisting of multi-antenna access points (APs) and single-antenna users. We consider maximizing energy efficiency (EE) of a MEC system, defined… read more here.

Published in 2023 at "IEEE Wireless Communications Letters"

DOI: 10.1109/lwc.2022.3215765

Abstract: In this letter, we study the user packet scheduling problem for deterministic mobile edge computing (MEC) systems aiming at minimizing the overall system task completion time. To reduce the time cost, we introduce three settings:… read more here.

Published in 2021 at "Applied Sciences"

DOI: 10.3390/app11167589

Abstract: To improve the resource efficiency of multi-access edge computing (MEC) systems, it is important to distribute the imposed workload evenly among MEC servers (MECSs). To address this issue, we propose a task redirection method to… read more here.
