This paper presents a proof-of-concept wireless sensor network for detecting and tracking friendly objects and detecting and localizing foreign objects. The network incorporates a novel sensor network methodology to Sense its surroundings, Decide in-network what the situation in its surroundings is, Act on this decision, and Communicate its results to a user (SDAC). The system also performs in-network data fusion and data reduction and demonstrates the use of an adaptable hardware and software platform. The end user is presented with a Geographical Information Systems (GIS) viewer showing when and where objects are detected. The viewer is able to display tracking information about friendly objects by searching a database for events involving specific friendly objects.
