A web-based two-layered integration framework for smart devices

Abstract

The explosions of Internet of Things industry have been bringing more and more smart devices (SDs) into business and people's daily life. This creates new opportunities to build applications that better integrate real-time state of the physical world and requires agility for the software to accommodate customers' requirements. Nevertheless, devices are usually provided by different manufacturers, and applications are independently constructed based on their own infrastructures with little interoperability. Web of Things concept has enabled the interoperability between devices by RESTful web service in a light-weight way; however, it make less efforts to discuss how to integrate devices into complex business environment. Service-Oriented Architecture and Business Process Management approach are becoming applicable to embedded real-world devices and provide flexible service composition. However, it is based on WS-* web service specification which is too heavy and complex for devices and not compatible to RESTful style. In such situation, integrating device into business application with simplicity and providing agility composition of service based on device are significant challenges. We propose a web-based two-layered integration framework that enables SD to integrate with each other via light-weight interface and other back-end applications into agile business process. A real-life use case on elderly care is studied in detail based on the framework.

“…In "P2P and Grid Computing: Opportunity for Building Next Generation Wireless Multimedia Digital Library" [2], a framework for wireless multimedia digital library is designed, by adopting peer-to-peer overlay networking technology to address the storage space problem and by using grid computing approach to maintain security. In "A Webbased Two-layered Integration Framework for Smart Devices" [3], a web-based framework is provided that enables smart devices to integrate with each other via light-weight interfaces and other back-end applications into agile business process, while a real-life use case on elderly care is studied in detail based on this framework. Finally, in "Combining Cloud and sensors in a smart city environment" [4], concepts and principles from cloud computing and sensing are efficiently combined and integrated to facilitate the design of a pervasive infrastructure, where new generation services interact with the surrounding environment, thus creating new opportunities for contextualization and geo-awareness.…”

Several examples exist where wireless sensor networks, mobile equipments, RFID tags, home appliances, cars, and many other daily objects talk to each other, exchange information, generate aggregated knowledge, and allow to quickly develop new advanced services for the final user.…”
