A location privacy system in mobile network using game theory

Abstract

The continuous dissemination of location information of mobile users has affected the security of mobile devices and also increased the location privacy vulnerability which necessitated the use of game theory approach to solve the problem. This research designs a location privacy system of n-player game that analyses the behaviour of mobile nodes in the network. Each player aims at maximizing its location privacy at minimum cost by strategically choosing series of actions in the game. The design was simulated using Java programming language configured on Windows 7 platform. The results of the games played were presented with analysis showing the strategies chosen by the mobile nodes. The players had opportunity of choosing perfect strategies as the number of players participating in the game increases thus, enhance the level of location privacy achieved by the players.
