Mobile healthcare applications: system design review, critical issues and challenges
This paper proposes a security framework with quality of service (QoS) mechanisms embedded in a Next Generation Internet architecture to support healthcare infrastructure with mobile wireless sensors. The framework shields the complexity of internetworking with a policy management system to subscribe quality of service and level of security. The framework also hides the intricacy of mobile wireless-networked sensors with a middle ware component to deliver sensing data and retrieve patient monitoring information. Complying with the Internet Design Philosophy, the complexity is pushed to the end processing nodes for healthcare information comprehension and manipulation. Both security and service requirements for healthcare infrastructure are achieved with the established architecture of Next Generation Internet.
