Mesh-based Cloud Data Storage & Management Framework for Internet of Things

The Internet of Things (IoT) is the network of physical objects, devices, vehicles, buildings and other items that enables these objects to collect and exchange data. One of the application domains of IoT is smart building where a number of things are efficiently interconnected in order to combine and integrate the physical world to the information space and to provide the services in an efficient way. In the smart building management systems, the data of building conditional monitoring are increasing rapidly. Facing with these massive, distributed, heterogeneous and complex state data, conventional data storage and management will encounter great difficulties. Conventional infrastructure uses centralized approach, expensive largescale server, disk array storage hardware and relational database management system; which leads to poor system scalability, higher costs, and essentially, is difficult to adapt to the requirement of higher reliability on realtime state data of the smart building applications. Accurate, fast, open, shared information system is the basis for the IoT applications. In this paper, we proposed a mesh-based data storage and management framework which provides reliable data storage and management of the vast amount of information in the IoT applications. We have evaluated and validated our approach by applying our cloud data storage and management framework in our cyber-physical test-bed, a facility which is intended to test innovative technologies for urban sustainability.
