Game theory for wireless sensor network security

Abstract

This paper presents a comprehensive study on applications of game theory to face the security problems in wireless sensor networks. The dynamic nature of WSNs makes them vulnerable to different security challenges. In the literature, three techniques have been proposed to protect WSNs from malicious nodes, cryptography, trust-based methods, and game theory. In this paper, we review the major game theory approaches to overcome denial-of-service attacks and selfish behaviors in wireless sensor networks; we propose at the end the fusion of cryptography techniques and game theory for more privacy and security. Finally, we discuss some limitations of game theory solutions in WSNs.
