Context-aware remote healthcare support system based on overlay network

Many countries are facing an ever-growing need to supply constant care and support for their disabled and elderly populations. So the importance to remote monitoring is becoming essential for looking after them. With an environment full of smart and cooperating artifacts will at the same time pose great risks to personal privacy. To protect personal information patient's data should be available irrespective of their location, but only to the authorized person. At the same time quality and reliability of transferring data is also important depending on the content of the data and the recipient. In this paper we propose a system where a personalized overlay network will be built in an ad hoc basis and links between different entities will be established according to the social relationship between the person under observation and the people at the other end and the situation of the observed person. The connected links will provide reliability, quality and other required characteristics according to the requirements specified by the members involved. For efficient cost and resource utilization, an on-demand network connection is considered for our proposed context aware ubiquitous healthcare system.
