Abstract:
Dynamic Spectrum Access (DSA) has been proposed to increase the spectrum utilization efficiency and to solve the spectrum scarcity problem. However, due to the spectrum sharing and opportunistic access nature of the DSA networks, they are more vulnerable to security threats like jammers. In this paper, we propose an anti-jamming technique in which the secondary network coordinator groups the secondary users in smart collations over the different channels. By utilizing cooperative communication, the secondary users in these collations can boost their transmission against the effect of the jammer. The interaction between the secondary network and the jammer is modeled as a modified Colonel Blotto game in which the secondary network coordinators acts as the defender and the jammer as the attacker. A fictitious play based algorithm is used to find the mixed Nash strategy equilibrium solution of the game. The results show that utilizing cooperative communication enhances the performance of the secondary users over using the direct transmission in two networks with two different objectives. Also, the result shows that increasing the number of secondary nodes rationally enhances the performance of low data rate nodes.
