Resource sharing is an issue for many different fields of applications, giving rise to the so-called "Tragedy of the commons." This is particularly important in reference to the upcoming Internet of Things, where selfish behaviors from individual users may jeopardize a cooperative network behavior, on which most network functions in this scenario rely. In this paper, we analyze two ways of splitting resources in the context of channel allocation for wireless systems. We describe the outcomes of the different strategies and we identify some criteria for the emergence of selfish behaviors in such games.
