Information game model for secure localization in wireless sensor networks

Recent years have witnessed an impressive growth in the technology of wireless sensor networks (WSNs). Being an essential technology of WSNs, localization is very important to the location-based applications and network protocols. Therefore, several reported studies have focused more attention on the secure localization. A paradigm that the benign anchors are compromised in the hostile battlefield environments, and turn into malicious nodes to pretend to be true anchor nodes and send false information to interfere with the correct localization procedure of ordinary nodes, is designed. To solve this problem, some effective approaches should be explored to ensure the security of localization and eliminate the adverse influence due to the malicious anchors. Therefore, in this paper, we propose a novel information game based secure localization approach for wireless sensor networks. The secure localization problem in hostile scenario has been transformed into an information game problem. Simulation results show that the proposed method is effective to secure localization.
