Study on the Design of Service Discovery System Based on IoT Device Extended Information

Internet of Things is emerging as a concept to integrate and expand Internet technologies. Internet of things is rapidly developing as sensing technology and wired/wireless communication technology develop. This study proposes a system for applying information generated by IoT devices to web services.

The study presents the processing methods of various information protocols and data generated from IoT devices and provides them to service brokers performing web service discovery based on the generated information so that they can be used for service discovery. The proposed method extracts and generates device information from IoT devices. Through the formal specification of the generated information, the service list is provided to the user using the QoS information and IoT information in web service discovery.

A service discovery system based on IoT information was proposed for the purpose of using search information when selecting web services by using information generated through collaboration between devices and devices and device interaction with users through extension of IoT environment. The proposed system complements the reliability and availability problems of the existing search methods. The information model for the IoT service is presented in three stages, and the information generated in the IoT environment is defined to be applicable to the web service through the formal specification of each stage. The purpose is to apply to web service discovery system based on defined IoT information so that users can select appropriate services.

By adding IoT devices information to the existing web service discovery method, the problem of QoS unilaterally provided by the provider is solved, and by presenting a list of services suitable for the user based on the information generated in the IoT environment used by the user, user satisfaction can be improved.
