In particular, the platform connects with a massive array of medical devices, consumer gadgets and applications to automatically import data. In addition, the user can manually add data, including weight, lab results, medications, menstruation dates, immunizations, medical procedures, and more. Furthermore, doctors can send data and files of their patients right into their Health Vault account. Thus, Health Vault provides the service of implementing an online and widely accessible personal medical record. Sensor Cloud[74]has been introduced as an infrastructure with the aims of managing physical sensors by connecting them to the cloud. In particular,Sensor Cloud bundles the physical sensors into virtual sensors where users can combine them together to achieve advanced results. SenaaS(Sensor-as-a-Service)[2]is another ap-proach that has been proposed to encapsulate both physical and virtual sensors into services according to the Service Oriented Ar-chitecture (SOA) approach. SenaaS mainly focuses on providing sensor management as a service rather than providing sensor data (collection and dissemination) as a service.
