A Smart Gateway Framework for IOT Services

With various connectivity and communication protocols, it is conceivable that all raw data from sensor devices can be made available in the Internet. However, this imposes a significant intricacy when dealing with the amount of information and the management of the devices. To alleviate the problem, this paper presents a design and implementation of a prototype IoT gateway framework that exposes high-level abstraction for accessing and manipulating the devices of an ambient environment and the data that they produce. Along with integrating and consolidating edge devices, the gateway framework enables the construction of high-level knowledge to represent the property of the environment and to support privacy protection. Thus, intelligent services, created with reasoning rules or event triggers, can be adaptable to application environment. To illustrate the capability of the IoT gateway framework, an application scenario and its performance evaluation are included in the paper.
