Computing Tasks Distribution in Fog Computing: Coalition Game Model

Files and medias are not the only existing content. Computing tasks output content that can be described, stored, cached and offloaded. In this paper, we investigated the problems of edge computing and offloading in fog computing networks. Edge devices have always been limited in computing capabilities. The problem of latency occurs frequently when having huge amount of data to be processed. In Considering a given number of fogs serving multiple users, this paper investigates the problems of distributing computational tasks among the fogs. We propose a coalition game based solution to motivate the fogs to work together and cooperate, which in turn processes huge amounts of data within a short delay. Simulation results shows that the proposed model offers better latency and improved load balancing of the fogs resources.
