Efficient cooperative detection for wireless sentinel networks

In this paper, we propose an energy efficient cooperative detection scheme for wireless sentinel networks monitoring for surreptitious wireless communications. Our solution exploits the multiuser diversity in the network by proposing a cooperative randomized monitoring approach for individual sentinel nodes, that leads to more efficient resource expenditure and good detection and intruder localization performance for the network. A game theoretic framework is proposed to analyze the achievable operating point for the system. Simulation results show very good detection performance together with increased localization accuracy and energy efficient operation.
