A non-cooperative game approach for intrusion detection in sensor networks

Abstract

In this paper, we propose a new technique for handling security issues in mobile wireless sensor networks. We define a non cooperative game between an attacker and the sensor network. The attacker and the sensor network are the players of the game, where each one tries to maximize its own payoff. The sensor network tries to defend the sensor nodes against intrusions. We formulate the attack-defense game as a two-player, nonzero-sum, non-cooperative game. and show that this game achieves Nash equilibrium, thus leading to a defense strategy for the network, and significantly increases the chance of detecting intrusions.
