PROJECT TITLE :

Cloud4sens: a cloud-based architecture for sensor controlling and monitoring

ABSTRACT:

This article discusses 2 strategies for managing sensing resources within the cloud and providing them as a service. The primary strategy follows the data-centric model, where the cloud offers environmental knowledge to its purchasers as a service, while not any knowledge of how information are measured and processed. The second strategy adopts the device-centric model, that allows the cloud clients to use a virtual sensing infrastructure that they'll customize for specific purposes. They can access sensed data and customise one or more virtual devices. The article additionally presents a cloud framework, referred to as Cloud4Sens, that combines each the info-centric and device-centric models, enabling the tip-user to settle on which sort of cloud service he needs. The proposed solution was designed in line with the Sensor Web Enablement (SWE) specifications defined by the Open Geospatial Consortium and exploits well-known technologies, like XMPP (Extensible Messaging and Presence Protocol) communications and X509 certificates.
