Demo abstract: Towards continuous tracking: Low-power communication and fail-safe presence assurance

Long-term fine-grained continuous tracking is still not feasible with today's algorithms and protocols. There are two main obstacles. The first is the need for efficient, low-power communication protocols. Many current protocols employ energy-expensive methods to achieve reliable communication for arbitrary traffic situations. The second challenge is the lack of a robust presence detection algorithm that differentiates between ambient packet loss and packet loss due to missing items. We will demonstrate a continuous tracking system using a simple communication protocol, Uni-HB, with the detection algorithms that we designed to yield low false alarm rates while achieving timely loss notification.
