The forthcoming generation of healthcare services will require advances in computing and Wireless Sensor Networks (WSNs) in order to leverage truly intelligent and adaptive features for smarter eHealth services. This paper proposes a multi-sensory cloud based system capable of monitoring and tracking the patient’s behavior with respect to his vital signs. The paper also showcases the proposed system on a real testbed, performing real-time vital signs data acquisition, processing, and monitoring. Keywords— eHealth; sensor network; vital signs; cloud computing; eWALL; I. INTRODUCTION The Internet-of-Things and cloud computing have a potential to support a number of different applications regarding users’ lifestyle, convenience, comfort, security, etc., and most importantly health. The smart-homes for eHealth incorporate different sensing devices such as fixed sensors for environmental monitoring and wearable sensors for activity and vitals detection. A complete end-to-end system for healthcare services besides devices should comprise local and cloud software and interfaces to provide end-to-end flow of medical data. The benefiters of the system can vary from the patients themselves, providing health information and guidance on how to improve their health, to caregivers and health institutions, for monitoring and tracking the patient’s behavior and his/her wellbeing. One of the main goals of the system is the timely diagnosis and treatment of the possible health issues. Especially important is the monitoring and tracking of the patient’s vital signs. Continua health Alliance (CA) [1] is a not-for-profit industry organization, aiming to provide end-to-end, plug-and- play connectivity of devices and services for health management and healthcare. This organization is working towards establishing systems with interoperable eHealth devices and services via its product certification program. Continua Health Alliance products make use of the ISO/IEEE 11073 standards for health data management. They provide USB, Bluetooth and Zigbee interfacing of connected medical devices including pulse oximeters, blood pressure monitors, thermometers, glucose meters, weighting scales etc. This paper proposes a CA facilitated multi-sensory cloud based end-to-end solution. The proposed solution/system monitors, tracks and provides services with respect to the patient’s vital signs. The paper also provides insights into the actual implementation and operation of the proposed system on a real-world testbed, performing real-time vital signs data acquisition, processing and monitoring. The paper is organized as follows. Section II introduces the end-to-end architecture for vital signs monitoring with the necessary functional blocks and interfaces. Section III provides details on the data acquisition process. Section IV elaborates on the intelligent processing and manipulation with the vital signs data and provides particular implementation results. Finally, section V concludes the paper. II. SYSTEM ARCHITECTURE This section presents the generic eWALL architecture (backend technology), with particular emphasis on the functionalities for smart vital signs monitoring. The eWALL architecture, as depicted in Fig. 1 consists of two main components, home environment and eWALL cloud.              Fig. 1. Generic eWALL architecture. The home environment is consisted of two core modules, a sensor network and a graphical user interface (GUI). The sensor network acquires information with respect to the environment, such as temperature, pressure, humidity, luminance, gasses etc., as well as information regarding the primary user’s wellbeing, such as the vital signs. The GUI represents the visual interface that facilitates the interaction between the primary user and the system. Moreover, the GUI This work was supported by the EC FP7 eWALL (610658) project. 525
