A REVIEW ON RELATIONSHIP BETWEEN IOT- CLOUD COMPUTING - FOG COMPUTING (APPLICATIONS AND CHALLENGES)

Many vital domains such as smart building, smart cities, healthcare, agriculture, and environment monitoring, take benefits from IoT (Internet of Things) technology emergence. Recently, the amount of IoT generated data becomes huge, creating many research challenges in data management topic, in another side, transmission of these amounts of data requires large bandwidth, and generate significant delay. From this vision, we prepare this paper to help new searchers interested in IoT data management topic, to find out a good starting point. For this reason, we shed light on IoT technology, and show its relationship with big data evolution scene, then show the importance of the new paradigm known as fog computing to overcome most of these problems. At first, we introduce the five elements of an IoT object and common communication models used by smart objects, then we discuss comparison of hardware IoT platforms, and recommendations to take into consideration while choosing a hardware IoT platform, in the next pages we introduce cloud IoT infrastructures, followed by a presentation of fog computing advantages and challenges.
