A Game Theoretical Analysis of Localization Security in Wireless Sensor Networks with Adversaries

Wireless Sensor Networks (WSN) support data collection and distributed data processing by means of very small sensing devices that are easy to tamper and cloning: therefore classical security solutions based on access control and strong authentication are difficult to deploy. In this paper, the authors look at the problem of assessing security of node localization. In particular, they analyze the scenario in which Vriable Multilateration (VM) is used to localize nodes and a malicious node (i.e., the adversary) try to masquerade as non-malicious. They resort to non-cooperative game theory and they model this scenario as a two-player game. They analyze the optimal players' strategy and they show that the VM is indeed a proper mechanism to reduce fake positions.
