Incentives and Resource Sharing in Spectrum Commons

Executive Summary

It has been suggested that light regulation in the form of etiquette protocols, device design and bargaining amongst users will suffice to mitigate a tragedy of the commons in unlicensed spectrum. In this paper, the authors propose a game theoretic model to examine this claim. In this game, each user decides whether or not to set up an access point, which operates on a particular (single) band. The effect of regulation is modeled in reduced form through transfers. A user, who sets up an access point, provides payments to each neighbor who does not and suffers a disutility depending on the number of interfering access points. A user, who does not set up an access point, receives payments from each neighbor that does.
