RestThing: A Restful Web Service Infrastructure for Mash-Up Physical and Web Resources

Abstract

In the field of Cyber Physical Systems and Pervasive Computing, physical resources and web resources can be easily handled and seamlessly integrated into our life. However, due to the heterogeneity of devices and tight coupling of individual information systems, the developers cannot easily create their specific applications by combining with physical and web resources. In this paper, we proposed Rest Thing which is a restful web service infrastructure based on REST principles in order to hide the heterogeneity of devices and provide a seamless way to integrate embedded devices with existing web applications. Besides, we implemented a prototyping system, which provided the restful accessible way of the wireless sensors, and built a demo application on the smart phone to collect and merge physical and web resources. Finally, we gave the performance evaluation of the prototyping system.
