Abstract.Wireless sensor networks (WSN) are practical implementations of distributed computing ad hoc wireless networks. WSN are typically empowered by scarce energy resources and limited computing power, they are mainly used for in situ data acquisition and monitoring of the deployment area. As such, they are susceptible to various forms of jamming, mostly but not exclusively, at the physical and data link layers. Of special interest are the moving jammers, which impose added strain on the WSN. In the present paper we developed a mitigation method that takes into consideration the jammer's behavior and accordingly adopts new routes, in order to maximize the WSN life. The model is an improvement of the well known LEACH energy-efficient routing protocol. In simulations, we have found that our protocol achieves a significant improvement of the WSN lifetime offering a proved improvement in the resilience of WSN against moving jamming attacks.
