Latency Minimization for Intelligent Reflecting Surface Aided Mobile Edge Computing

Understand

Computation off-loading in mobile edge computing (MEC) systems constitutes an efficient paradigm of supporting resource-intensive applications on mobile devices.

• However, the benefit of MEC cannot be fully exploited, when the communications link used for off-loading computational tasks is hostile.
• Fortunately, the propagation-induced impairments may be mitigated by intelligent reflecting surfaces (IRS), which are capable of enhancing both the spectral- and energy-efficiency.
• Specifically, an IRS comprises an IRS controller and a large number of passive reflecting elements, each of which may impose a phase shift on the incident signal, thus collaboratively improving the propagation environment.
