5G framework based on multi-level edge computing with D2D enabled communication

Abstract

There is no doubt that the release of the fifth generation of the mobile cellular system (5G) becomes a great demand year by year, especially with the massive increase of heterogeneous Wireless devices. The 5G network will be a platform for wide variety of industries. Designing of 5G cellular system faces various challenges related to the capacity and traffic. One way to solve these challenges is to employ device-to-device (D2D) communication and mobile edge computing (MEC). Employing these technologies offload the core network and increase the capacity of the system. In this work, we propose a frame work for the 5G cellular system based on D2D communication and multi-level cloud units employed at the edge of the cellular network. The system employs four levels of cloud units with various hardware capabilities. The D2D communication is used as the communication technology in the first level of clouds. Employing D2D together with multi-level edge cloud units achieves varies benefits to the system as the system level simulation provides.
