Big-Sensor-Cloud Infrastructure: A Holistic Prototype for Provisioning Sensors-as-a-Service

The proposed work relates to the development of Big-Sensor-Cloud Infrastructure (BSCI) that enhances the usability and management of the physical sensor devices. Traditional sensor networks are manufactured in a proprietary, vendor-specific design, and cannot handle application switching dynamically at runtime due to the presence of monolithic kernel. Thus, the applications are inaccessible to the common people who do not own physical sensor devices. Recently, sensor-cloud infrastructure has been viewed as a substitute for traditional sensor networks. However, with the increasing growth in the velocity, variety, and variability of data, the management becomes a serious concern and difficulty. Thus, existing systems are not able to capture, analyze, and control the present data efficiently, in real-time. BSCI is a distributed framework for "Big" sensor-data storage, processing, virtualization, leveraging, and efficient remote management. The framework interfaces between the physical and cyber worlds, thereby acquiring real-time data from the physical WSNs into the cloud platform. This data are processed and delivered to the end-users as a simple service - Sensors-as-a-Service (Se-aaS). Multiple organizations with heterogeneous demand can be successfully served with Se-aaS. From a user-perspective, BSCI allows the naive users to envision the typical sensor devices as simple accessible services like electricity, and water.
