An Effective Scheme to Detect Jamming attacks on the Physical Layer of WSN Using Localization Algorithms (Convex Hull & RSSI)

Abstract

Jamming is one of the main attacks on WSN physical layer, detecting and preventing such an attack is a major challenge, there are many known methods to solve jamming attacks related issues in WSN among which are: spread spectrum, frequency hopping and the use of localization algorithms, which has proven to be one of the most effective methods to localize jammers. We proposed the use of Convex Hull algorithms (mainly Divide and Conquer algorithm and the Quick Hull algorithm) combined with the Receive Signal Strength Indicator algorithm in order to address these attacks. Our solution consists of using RSSI to identify the jammed nodes location and CH to isolate these jammed nodes from the rest of the network.
