A key application of sensor networks in smart environments is in monitoring activities of people. We develop several scenarios in which ultrasonic sensors are used for patient and elderly monitoring. In each scenario, we apply different algorithms for data fusion and sensor selection using quality-based or time division approaches. We have devised trajectory-matching algorithms to classify trajectories of movement of people in indoor environments. The trajectories are divided into several… CONTINUE READING
