In this paper, we study indoor passive tracking problem using wireless sensor networks, in which we assume that a target being tracked is clean, i.e., there is no any equipment carried by the target, hence, the tracking procedure is considered to be passive. We first show that received signal strength indicator and link quality indicator are not as effective as expected for passive detection (tracking) through our extensive testbed studies, and further propose to utilize light to track targets… CONTINUE READING
