Cell-based sensor network for complex monitoring at home of patients with chronic diseases

In order to improve the quality of life for the elderly or people with chronic disease, the paper proposes a smart cell-based sensor network for home monitoring. The cell is considered to be a small sensor network which is situated into the patient´s house. It is composed of mobile and fixed sensors, disposed on five sensor groups. Each group is actually a network of dedicated sensors: ambient sensor network, body sensor network, emergency sensor network, visual sensor network and sensor network dedicated to on request - physiological parameters monitoring. Sensor networks cooperate with each other within the cell to increase the efficiency of monitoring, to decrease energy consumption and radiation level. Adaptive rates of acquisition and communication are used. Some experimental results are presented in the last section.
