Jamming attacks have become prevalent during the last few years, due to the shared nature and the open access to the wireless medium. Finding the location of a jamming device is of great importance for restoring normal network operations. After detecting the malicious node authors want to find its position, in order for further security actions to be taken. The goal in this paper is the design and implementation of a simple, lightweight and generic localization algorithm. The scheme is based on the principles of the gradient descent minimization algorithm. The key observation is that the Packet Delivery Ratio (PDR) has lower values as they move closer to the jammer.
