The advancement in technology for patient monitoring and smart living environments is making a huge impact on providing health care for the elderly and needy population. An energy efficient context aware system for sensing and reporting events based on wireless sensor networks (WSN) is presented in this paper. It is demonstrated that it is possible to build and deploy power efficient systems with an extended battery life by exploiting the recent technological innovations and properly using the architectural framework for supporting WSNs. The system evolves with highly localized computations aided by the contextual information which helps in detecting events and alerting the care provider for only the positive events.
