Enabling low latency mobile edge computing through millimeter-wave links
Mobile Edge Computing (MEC) brings information technologies closer to mobile users by empowering radio base stations with additional computational capabilities. Even if the single base station may have limited computing or caching capabilities, the coordination of multiple base stations can give rise to a powerful and scalable distributed system able to deliver services with low latency.
A further major thrust to this framework comes from the usage of millimeter-wave (mmW) communications as a wireless backhaul between base stations or even for the mobile access. In this talk, we will show how MEC can benefit from mmW in optimizing computation offloading from the mobile user to nearby base stations, minimizing the energy necessary to run mobile applications remotely under strict latency constraints. We will also explore how these benefits vary as a function of the carrier frequency, incorporating imperfect knowledge of the steering angles used for beamforming and intermittent channel models, suitable for mmW beam forming channels.
