摘　　要：Jamming attack can severely affect the per-formance of Wireless sensor networks （WSNs） due to the broadcast nature of wireless medium. In order to local- ize the source of the attacker, we in this paper propose a jammer localization algorithm named as Minimum-circle-covering based localization （MCCL）. Comparing with the existing solutions that rely on the wireless propagation pa-rameters, MCCL only depends on the location information of sensor nodes at the border of the jammed region. MCCL uses the plane geometry knowledge, especially the minimum circle covering technique, to form an approximate jammed region, and hence the center of the jammed region is treated as the estimated position of the jammer. Simulation results showed that MCCL is able to achieve higher accuracy than other existing solutions in terms of jammer＇s transmission range and sensitivity to nodes＇ density.
