Energy-Efficient Predictive Jamming Holes Detection Protocol for Wireless Sensor Networks

Wireless sensor networks (WSN) are practical implementations of distributed computing ad-hoc wireless networks. Typically empowered with 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, at the physical and data link layer. Of special interest are the moving jammers, which impose added strain on the WSN. We developed a detection protocol that takes into consideration the jammer´s behavior and accordingly adopts new routes, in order to maximize the WSN life. We simulated our algorithm, which is an improvement of the well known LEACH energy- efficient routing protocol, vs. the original LEACH. We have found a significant improvement of the WSN lifetime, offering a proved improvement in the resilience of WSN against moving jamming attacks.
