Edge Node Cooperation and Resource Sharing in Mobile Edge Computing

As edge computing undergoes ongoing development propelled by the advancements in Internet of Things and mobile communication technologies, the issue of edge node cooperation and resource sharing needs to be investigated. In this paper, the issue of edge node cooperation and resource sharing is modeled as a two-layer framework. In the lower layer, a heuristic matching algorithm between users and edge nodes is developed, and a resource sharing algorithm among edge nodes in the same coalition is proposed. In the upper layer, a coalition formation algorithm is designed based on the coalition game. Simulation results show that the proposed algorithms reduce the network cost effectively compared with non-cooperative scheme.

I. Introduction

As a promising edge technology, mobile edge computing (MEC) plays a vital role in improving mobile network performance by bringing computation and storage closer to end-users, allowing seamless resource sharing and optimization of latency-sensitive applications [1], [2].
