Demonstration of a Wireless Sensor Network for Real-Time Indoor Localisation and Motion Monitoring

This paper describes our demonstration of a wireless sensor network for monitoring human motion and position in an indoor environment. Mobile sensor nodes comprising mote-type devices, along with inertial sensors are worn by persons moving inside buildings. Motion data is pre-processed onboard mobile nodes and transferred to a static network of seed nodes using a delay tolerant protocol with minimal radio packet overhead. A Monte Carlo based localisation algorithm is implemented, which uses a person´s pedometry data, indoor map information and seed node positions to provide accurate, real-time indoor location information.
