Low-cost ground sensor network for intrusion detection

Abstract

Perimeter surveillance of forward operating locations, such as Forward Arming and Refueling Points (FARPs), is crucial to ensure the survivability of personnel and materiel. FARPs are frequently located well outside the protective cover of the main forward operating bases. Therefore, they must provide their own organic perimeter defenses. Such defenses are manpower intensive. Our research investigates how cheap, remote, unattended sensors using commercial off-the-shelf (COTS) components can help reduce the manpower requirement for this task and yet not compromise the security of the operating location. We found Internet of Things (IoT) platforms such as Raspberry Pi, paired with passive infra-red sensors and cameras, to be useful in this application. We built a prototype sensor system, tested it in a simulated field environment, and evaluated its performance. We conclude that COTS IoT platforms have much potential to support surveillance of FARPs and other forward operating locations.
