Abstract

When large-scale wireless sensor networks are deployed in hostile environments, the adversary may compromise some sensor nodes and use them to generate false sensing reports or to modify the reports sent by other nodes. Such false events can cause the user to make bad decisions. They can also waste a significant amount of network resources. Unfortunately, most current security designs have drawbacks; they either require their own routing protocols to be used, or lose legitimate events stochastically and completely break down when more than a fixed threshold number of nodes are compromised. We propose a new method for detecting false events that does not suffer from these problems. When we set the probability of losing legitimate events to 1%, our proposal method can detect more false events than related method can. We demonstrate this by mathematical analysis and simulation.
