ABSTRACT

IoT (Internet of Things) is a new paradigm which provides a set of new services for the next wave of technological innovations. IoT applications are nearly limitless while enabling seamless integration of the cyber-world with the physical world. However, despite the enormous efforts of standardization bodies, alliances, industries, researchers and others, there are still numerous problems to deal with in order to reach the full potential of IoT. These issues should be considered from various aspects such as enabling technologies, applications, business models, social and environmental impacts. In focus of this paper are open issues and challenges considered from the technological perspective. Just for clarification, we put in light different visions that stand behind this paradigm in order to facilitate a better understanding of the IoT’s features. Furthermore, this exhaustive survey provides insights into the state-of-the-art of IoT enabling and emerging technologies. The most relevant among them are addressed with some details. The main scope is to deliver a comprehensive overview of open issues and challenges to be tackled by future research. We provide some insights into specific emerging ideas in order to facilitate future research. Also, this paper brings order in the existing literature by classifying contributions according to different research topics.

 Conclusion

IoT needs to enable a seamless connectivity anytime, anywhere by anyone and anything to provide intelligent services including identifying, sensing, networking, processing and visualization capabilities. This concept brought many new possibilities for large-scale services and products development which caused a massive wave of innovations and new business opportunities. Various visions and approaches, as well as the lack of coordination between standards and technologies, lead to the fragmentation of IoT industries which cause a set of new challenges to be tackled by future research. IoT-based solutions have become more advanced and sophisticated while there is no a comprehensive framework with integrated all standards and technologies. This open several issues which arise due to an increasing number of connected devices, integration of various technologies, increased traffic demands with new traffic models, raw data storage and processing demands, privacy and security risks, etc. This paper clarified different IoT visions and definitions on the basis of referenced literature. Also, the paper provides insights into the IoT enabling technologies by presenting the functional domains with key utility factors. Besides existing solutions, there are many emerging technologies which empowers IoT systems with numerous of new capabilities and functionalities. This paper summarized the current state-ofthe-art of IoT enabling and emerging technologies in order to provide a comprehensive list of open issues with some details. Furthermore, this is used to provide some future research directions. We performed the classification of previous research and present a literature pool to bring order in the literature by classifying existing works according to different research areas. Therefore, this paper is mostly focused on issues related to the IoT enabling and emerging technologies.
