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.
Introduction
IoT (Internet of Things) is based on integrations of various processes such as identifying, sensing, networking, and computation. It enables large-scale of technological innovations and value-added services which personalize users’ interaction with various “things”. There are numerous IoT applications that can be grouped into various domains such as health, traffic, logistics, retail, agriculture, smart cities, smart metering, remote monitoring, process automation, etc. Despite the enormous progress in different research fields including architectures, standardization, emerging technologies, security, etc. we consider that IoT is still in the nascent stage of its development. This article provides reports on the state of art, current trends and open issues according to the main IoT visions and enabling technologies. We conducted a review of up-to-date reference literature including journal papers, conference's papers, standards, project reports, white papers and reports from industries. Thus, we provide useful guidelines for readers to understand IoT paradigm and open issues in order to provide perspectives for future research and development. To discuss research trends, we need to understand what IoT really means and to examine its impact on everyday life, industry, and new business models. We are still in nascent stages where everybody is trying to interpret IoT according to their visions and needs [1]. Because of that, there is no universal definition of IoT and existing visions are fuzzy. Also, there are some other terms related to IoT such as IoE (Internet of Everything), WoT (Web of Things), CoT (Cloud of Things), M2M (Machine to Machine), etc. Some authors consider these terms have the same meaning but the majority of authors distinguish these meanings according to particular vision [2]. We do not include deep analysis of different visions but we present some definitions so that the reader can gain an overall view of IoT.
