Nowadays, the integration of wireless sensor networks with cloud computing is of great interest to healthcare research and industry. In this context, the design of sensor clouds enhances the reliability, extensibility, scalability, and availability of several WSN applications.   This paper proposes a novel Sensor Cloud architecture to monitor high-risk patients. On top of the physical sensors, we build virtual sensors with respect to the medical staff's demands. These virtual sensors are dynamically created and updated based on the patient's location and health status, and also depending on the occurrence of sensitive events related to the status of the associated physical sensors. In addition to that, the configuration of virtual sensors is enriched with new functions of monitoring, maintenance, power saving and security to enhance their use. A simulation is conducted to assess the effectiveness of the proposed architecture.
