  Computation offloading in multi-access edge computing (MEC) is an effective
paradigm for enabling resource-intensive smart applications. However, when the
wireless channel utilized for offloading computing activities is hostile, the
proper advantages of MEC may not be completely realized. Intelligent reflecting
surface (IRS) is a new technology that has recently attracted significant
interest can optimize the wireless transmission environment in a programmable
way and improving the connectivity between user equipment (UE) and base station
(BS). In this paper, the performance of MEC architecture is analyzed
considering both IRS-assisted and without IRS communication scenarios in the
context of the urban micro cellular scenarios. The research obtained that the
deployment of IRS can reduce the spectrum and energy consumption significantly.
