In the fourth edition of the IEEE conference at Fog and Mobile Edge Computing (FMEC) in Rome, from June 10th to 13th, Isaac Lera presented the paper entitled "Analyzing the Applicability of a Multi-Criteria Decision Method in Fog Computing Placement Problem".

This work, framed under the scope of the national project ORDCOT (TIN2017-88547-P AEI / FEDER, UE) analyzes the design of different Fog scenarios in addition to the problem of placement. In Fog computing the placement selection of services in network devices with computational and storage functionalities is an NP-hard problem. In the literature, most of the approaches try to find the best allocation for each service but this computational effort requires a lot of resources and a global and static vision of the environment. Multi-criteria decision methods is an activity which helps to make decisions mainly in terms of choosing, ranking or sorting the actions. The ingredients of MCDA are a finite or infinite set of actions (alternatives, solutions, courses of action,...), at least two criteria, and, obviously, at least one decision-maker (DM). There are two important outranking family methods: PROMETHEE and ELECTRE.

Thus, we analyse the design of Fog scenarios and the placement problem using Electre III. In this exploratory study, we model a Fog environment to apply a decision model for determining which alternatives are the most suitable in each application deployment. We compare the results with the weighted average to analyse the applicability of Electre III method in the Fog placement problem. We design a dynamical scenario in which new users appear along with the simulation and we use the latency, hop count, cost, deployment penalty and energy consumption criteria to rank placement alternatives. This approach enables the study of how the characteristics of the resources have to be distributed, that is, how to design Fog scenarios, in order to make the allocation of applications more efficient.

FMEC 2019 conference aims to investigate the opportunities and requirements for Mobile Edge Computing dominance. In addition, it seeks for novel contributions that help mitigating Mobile Edge Computing challenges. That is, the objective of FMEC 2019 is to provide a forum for scientists, engineers, and researchers to discuss and exchange new ideas, novel results and experience on all aspects of Fog and Mobile Edge Computing (FMEC). FMEC is Technically Co-Sponsored by IEEE Italy Section, IEEE SMC Italian Chapter and Italy Section VT/COM Joint Chapter
