Patent number: 10009410Abstract: Description files and web service protocols for actuating things on Internet of things (IoT) are proposed. Essentials of every thing on IoT (‘IoT thing’) are defined in a description file. The description file is lightweight, versatile and standardized for web services. Thus, the IoT thing can be communicated through its protocol described in the description file. Therein, a keyword replacement method is used. In a command sent by a user at a client end, a specific keyword is used to replace an essential in the description file. Then, a complete message based on the protocol is generated to control the IoT thing. The present invention uniformly uses the same way for operating and managing IoT things of all brands and solving heterogeneity. The present invention significantly reduces development cost and may work out an automatic, high-performance and interoperable IoT ecosystem with applications.Type: GrantFiled: August 4, 2016Date of Patent: June 26, 2018Assignee: NATIONAL CENTRAL UNIVERSITYInventors: Chih-Yuan Huang, Cheng-Hung Wu
