Jamming attacks could cause severe damage to Wireless Sensor Networks (WSNs).Once jamming attack occurs, the most urgent work is to get the positioninformation of the jammer. Then safety measures to eliminate the jammingeffects can be devised. In this paper, the jammer localization is conducted bygeometric covering method to achieve a low energy consumption. And utilizingthe power of the jamming signal received by the boundary nodes, a compensatingmethod is composed to reduce the estimating error of the jamming area. At lastthe localization is conducted by extracting the minimum covering circle of thecompensated victim area. Simulations are conducted to test the localizationaccuracy with the impact of node density, jamming region and radius. Resultsshow that this localization method achieves both good precision and low energyconsumption.
