Séminaire Méthodes présenté par Wilfried Yoro le jeudi 26/4 après midi

Quand : Le jeudi 26 avril 2018 à 14h00
Où : la salle A05, à Télécom SudParis (Evry)

Wilfried Yoro, ancien doctorant de Télécom SudParis, fera un séminaire sur "le partage de la consommation d’énergie entre différentes catégories de service dans un réseau mobile, en utilisant la valeur de Shapley". Vous y êtes cordialement invités.

Résumé :
"The topic of energy consumption in networks is raging for environmental and economical stakes notably. One can find many works in the literature dealing with energy consumption of networks, for optimization purposes for instance. Very few works however tackle the issue of energy consumption per service category, which is of a great interest to understand the responsibility of each service category in the whole energy consumption. This is a tricky issue as it applies to both the variable and fixed components of energy. Indeed, energy consumption is composed of two components : a fixed and a variable components. The former is consumed irrespective of traffic while the latter is consumed proportionally to traffic. The share of a service category in the variable component is quite easy to estimate as it is proportional to the service traffic proportion. As of the fixed component, one can share it using several approaches : equal, proportional, etc. An equal sharing puts too much weight on small service categories and would prevent introduction of new ones. Proportional sharing puts too much weight on big services, undermining their role as driving players for the network deployment and operation. We propose in our work to use cooperative game theory concept Shapley value in order to strike a good balance between service categories in terms of responsibility. Small service categories get a lower responsibility compared to a uniform sharing and so do big service categories compared to a proportional sharing."
