IoT device and service discovery framework

Abstract

Internet of Things (IoT) is a unique domain which works on various aspects, which is blanketed, interconnected and thereby enables the humans to interact with the web services and creates a smarter world. There is severe problem in the unified way for discovering IoT devices and services in the present existing infrastructure. The current device centric approach is not in consistent with the growing network. There is no standard method which allows the user to find IoT devices and services in a single framework. Users looking for services will not be aware of potential services available to satisfy their needs. The proposed concept uses unified service discovery broker based architecture using web services. Broker based architecture allows the different providers to register their devices and services at one place and based on the user query, matchching of suitable device and appropriate service will be done and the service data corresponding to the specific query of the user will be provided by using semantic search. Hence, the user can find in a single framework the registered devices and services separately which will be bound together to process the IoT device data stored on cloud. In future, IoT applications would be deployed in several domains like home automation, smart cities, intelligent transport and e-health. Complex service request made by the user can also be resolved using service composition to get the final result.
