Abstract
Due to the increasing interest in collecting data related to physical activity habits and behavior of people, wireless sensor networks have emerged as one of the most appropriate technologies for applications that focus on the interest of health care and assisted living. DIA system (in Spanish, Dispositivo Inteligente de Alerta) has developed devices which detect behavior patterns from their users and use them to take alert actions when happen significant variations on these patterns. To sum up, DIA deploys a minimum set of sensors with sensory capabilities via wireless communications interface and according to a predefined semantics. In this paper, we prolong the battery life of wireless devices DIA by means, firstly optimizing the energy consumption of its communications, secondly adapting the firmware that performs the monitoring tasks and processing the information acquired by wireless devices, keeping or improving the quality of service provided. For this, we have used source code libraries that provide a complete source code communication protocol stack and TinyOS-2.1.1 as operative system.
