Wireless sensor networks supporting context-aware reasoning in assisted living

The large increase in aging population implies that automatic home monitoring will represent a major challenge for the near future. In this paper we describe an "intelligent" home environment in which modern Wireless Sensor Networks (WSN) technologies allow constant monitoring of a patient in a context-aware setting. Data collected and manipulated by the WSN support reasoning aimed at understanding the evolution of patient's health state and home environment, even when a limited number of unobtrusive, heterogeneous sensors is available.
