Abstract
This paper investigates the system performance of an intelligent reflecting surface-assisted mobile edge computing (MEC) network under Nakagami-mfading channel with an uplink non-orthogonal multiple access (NOMA) scenarios. The considered system consists of an access point (AP), two NOMA users, i.e., a cell-center user and a cell-edge user, and a two-dimensional passive element array of the intelligent reflecting surface (IRS). Specifically, we consider the IRS to act as a relay to help cell-edge users offload tasks to the AP. We derive closed-form expressions of the successful computation probability (SCP) to evaluate the system performance. Furthermore, we analyze the ceiling SCP when the system operates in the high-SNR regime to clarify the system further. Finally, we investigate the impact of critical system parameters on the behavior of this considered system to look insight into the performance. The simulation results confirm the accuracy of our analysis.
