An OSGi-based heath service platform for elderly people

With the rapidly ageing population in most countries, the health and safety issues become the primary concern for elderly people because ageing is often associated with physical and cognitive impairments. In order to provide intelligent assistive health services for elders, in this paper, we propose an integrated OSGi-based service platform that can aggregate a variety of health assistive services, including health status monitoring, automated diagnosis and prognosis, and personalized health instruction by leveraging either stationary biosensors deployed in domestic settings or mobile sensing artifacts carried by elders. The assistive services in this integrated platform are able to help elders sustain and enhance health condition and quality of life with personalized health support. Our proposed platform is highly scalable and reusable by exploiting the component-based architecture of OSGI service framework, new services can be easily added into the platform according to individuals' needs and requirements. An implemented prototype system and the relevant performance evaluation are also presented.
