title: Energy efficient contextual sensing for elderly care.
abstract: Technology assisted safe living has great potential in revolutionizing the way healthcare is provided to elderly and needy population. A wireless sensor network (WSN) based system for sensing and reporting events based on context 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 transmitting only positive events where care providers may need to be alerted.
