In the recent period, the development of technology resulted in wide appearance and popularity of smart devices, including smart phones and low-power computing devices supported by small sensors that operate either in authonomous way or provide an extension of conventional devices and thus make them "smart". Such devices correspond to IoT (Internet-of-Things) paradigm, where all of them have common property - they are continuously connecting to world wide web and are using it as a communication channel to send and receive data about several quantities (i.e. location, movement, temperature, etc.), where these interconnected devices act as a whole. Nowadays, integration of such devices becomes of great importance also in business environment since consideration of data acquired in real-time enables implementation of new and advanced functionalities that were not applicable before. Thus, such real-time collected data can significantly improve services in terms of business and process management, customer relationship management, logistics, automatization, localization, security, as well as other information systems. Project is focused on integration of IoT smart sensors and devices by SaaS (Software-as-a-Service) and by exploiting and joining positive properties of both aspects, one of the main objectives is to build a prototype platform that provides similar level of self-service and automatization in the field of the integration of IoT devices by SaaS services.
