Collaborative spectrum sensing has been proposed recently to improve the sensing performance in Cognitive Radio networks. However, cooperative sensing will also introduce extra cost to the collaborator, such as the cooperative time and energy consumption. In reality, whether the rational secondary users have incentive to join the collaboration depends upon whether the benefit of the collaboration could outweigh the cost. In this paper, the authors model it as the Cooperative Spectrum Sensing Game (CSSG). In this game, every secondary user could choose to collaborate or not in each time slot, and the payoff is measured in terms of data throughput.
