Delivery of healthcare services to the people living in remote places is a challenging task. A remote healthcare framework has been proposed in our earlier work based on sensor-cloud technologies. This paper explains the scenarios for deployment of such a framework in a remote healthcare delivery system. In our sensorcoud environment we propose to create virtual sensors and offer them on-demand to the health-care service providers for use in their services. In this paper, we discuss the purpose

... of using virtual sensors in healthcare domain and demonstrate how additional responsibilities that cannot be handled by physical sensor devices, can be delegated to virtual sensors in order to improve the efficiency of the system. Results of preliminary deployment of virtual sensors in two scenarios are discussed within limited scope and their advantages and related issues are put forward for future implementation of the sensor-cloud infrastructure.
