Virtualization of healthcare sensors in cloud

Web enablement of sensors is found to improve healthcare applications. However usage of too many physical sensors are limiting the mobility of the patients and has serious drawbacks like huge power consumption, heavy weight, health hazards and high degree of discomfort. To overcome these problems, this paper proposed a virtual sensor that computes the blood pressure of patients using a limited number of physical sensors. The sensor data are ported to cloud for achieving scalability, elasticity, on-demand service provision and availability. The developed virtual sensor has shown an accuracy of about 95% when tested on patients with normal vital sign parameters.
