Abstract:In cognitive radio networks, security against eavesdroppers is a critical issue. In this paper, we consider a scenario in which the primary transmitter selects one secondary transmitter to act as a relay to enhance the security of communication. And as a reward the primary transmitter allows the selected secondary transmitter to access its spectrum. We first formulate the problem as a stackelberg game with the primary transmitter and the selected secondary transmitter as the leader and the follower respectivel… Show more
