A Bayesian Game Analysis of Byzantine Attacks for Wireless Cognitive Sensor Networks in Smart Grids

Abstract

In this paper, we propose a revolutionary communication paradigm—Wireless Cognitive Sensor Network (WCSN) — to solve these problems. We analyze the incentives to introduce WCSN in smart grids and review the main research work with respect to Byzantine attacks in wireless cognitive sensor network. Furthermore, we provide some preliminary discussions on Bayesian game and wireless cognitive sensor network. More importantly, we propose a Bayesian game model for the Byzantine attacks of wireless cognitive sensor network in the smart grid and present a detailed equilibrium analysis of the interactions between malicious secondary users and honest secondary users. Analysis results demonstrate that rather than focus on penalties, regulators would be wise to ensure that the gain from challenging is significant and the cost of challenging is small, as this reduces the probability of sending false readings.
