Border surveillance is one of the high priority in the security of countries around the world. Typical and traditional border\nobservations involve troops and checkpoints at borders, but these do not provide complete security. One effective\nsolution is the addition of smart fencing to enhance surveillance in a Border Patrol system. More specifically, effective\nborder security can be achieved through the introduction of autonomous surveillance and the utilization of wireless sensor\nnetworks. Collectively, these wireless sensor networks will create a virtual fencing system comprising a large number\nof heterogeneous sensor devices. These devices are embedded with cameras and other sensors that provide a continuous\nmonitor. However, to achieve an efficient wireless sensor network, its own security must be assured. This article\nfocuses on the detection of attacks by unknown trespassers (perpetrators) on border surveillance sensor networks. We\nuse both the Dempsterââ?¬â??Shafer theory and the time difference of arrival method to identify and locate an attacked node.\nSimulation results show that the proposed scheme is both plausible and effective.
