Dual-mode wireless sensor network for real-time contactless in-door health monitoring

Due to the ageing population, real-time and autonomous health monitoring is an emerging priority in ambient assisted living. In this work, a wireless sensor network is proposed for home environments by which the sensors are dualmode radars, enabling concurrent remote localization of a person (i.e., without use of a tag) and fall detection. We elaborate on the network architecture, and in particular on the signaling as to enable real-time data processing (i.e., max. delay is 0.3 s) combined with radar-based wireless sensing. The approach is successfully demonstrated experimentally.
