Energy-efficient ambulatory activity monitoring for disease management

Technology assisted health and disease management has a potential of producing high quality life in various segments of population. A wireless sensor network (WSN) based system for sensing and reporting ambulatory activity for patients is presented in this paper. It is demonstrated that by proper use of architectures for supporting WSNs and by exploiting very recent technological advances, it is now possible to build and deploy extremely energy efficient systems with very long and dependable battery life. The system evolves over most existing approaches by highly localizing the computations for detecting events and intermittently transmitting data related to activities. The paper describes design of the system and analysis for energy efficiency.
