Middleware technology research and interface design based on internet of things

Abstract

With the advent of Internet of Things (IoT) technology, communications between physical objects and humans become realistic, and smart devices can be monitored and controlled remotely. It promotes the development of smart home, smart city and even smart planet, which greatly improves the quality and efficiency of human life. As a kind of common services, middleware technology plays an importance role in IoT system. This paper firstly introduces the research background of IoT and middleware technology. Then three main middleware access scenes are analyzed in IoT system, which is determined by the sensing device functions. Lastly, this paper defines the middleware interface, and proposes the interface design method. The middleware interface is classified into three categories: device side interface, application side interface and middleware management interface, in which device side interface defines the data transmission method between the device layer and the platform layer; application side interface defines the middleware opening resources and services between the application layer and the platform layer; and middleware management interface is mainly for devices and middleware management functions. It indicates the message interaction process, and separates different message information, thus improving the data transmission efficiency and enhancing the services open ability of IoT system.
