A Distributed Cooperative Attack on the Multi-Channel Spectrum Sensing: A Coalitional Game Study

In this paper, a distributed cooperative attack on multi-channel cooperative spectrum sensing is proposed. In the proposed attack, attackers play two coalitional games to maximize the number of invaded channels in a distributed manner. In the first game, attackers play with their fellow ones to allocate an optimal number of attackers for each channel, while in the second game, they play in the coalitions with other honest cognitive radios so as to conquer as many channels as possible. Simulation results show that the proposed attack can considerably decrease the number of available channels with a low attack cost.
