Abstract Spectrum sharing in unlicensed bands is expected to become an increasingly signicant research problem. With the proliferation of IEEE 802.11 wireless local area networks, and other future radio systems using the unlicensed bands, spectral coexistence of dissimilar radio systems has to be addressed in the future. Coexistence can be achieved with the help of spectrum etiquette, or alternatively by implementing new communication protocols and dening common spectrum coordination channels. In this paper, we investigate how two independent wireless networks may share spectrum without direct coordination and information exchange. We start with illustrating our previously introduced stage-based game model of such scenarios. The application of game models allows us to analyze the problem as a competition of players: Within radio resource sharing games, payoff-maximizing players represent wireless networks. Decisions that players repeatedly have to make are about when, and how often, to attempt medium access. In this papers analysis, we use an established notation to describe multi-stage strategies that determine players decision-making. Should radio networks cooperate? Or, should competing radio networks ignore the presence of other radio networks? What is the expected outcome in a repeated interaction? This paper shows that trafc requirements imposed by services and applications determine the selected strategies, which pursue cooperation or ignore other radio systems.
