Non-intrusive Tracking of Patients with Dementia Using a Wireless Sensor Network

As a consequence of the aging of the world population, society and governments must face major challenges regarding people´s health. In recent years, researches have been interested in investigating how the technology can be used to improve the healthcare and assistance of patients with dementia, as the Alzheimer´s disease. In this paper, we propose a nonintrusive pervasive model to assist patients with dementia, based on the use of a wireless sensor network. Using high availability and low cost binary sensors, the proposed model is able to determine in real-time the location of a patient, and to emit alerts if one leaves a safe place without supervision.
