This paper presents the Nash equilibrium problem for a multipoint-to-multipoint network whose nodes aim at maxi- mizing their energy efficiency (EE). The equilibrium problem is reformulated as a max-rate equilibrium problem with cou- pling among the strategy sets of the players. Unfortunately, the analysis of this kind of games can not be addressed us- ing traditional theoretical tools. To cope with this challenge, the equilibrium problem is formulated as a quasi-variational inequality for which existence results are given. This formu- lation provides us with all the mathematical tools necessary to devise novel distributed algorithms.
