The Internet of Things (IoT) is a vision of a future Internet where physical objects, from banknotes to bicycles, are connected through a network and can actively participate in the Internet, exchanging information about themselves and their surroundings. This will provide immediate access to information about the physical world and objects, leading to innovative services and increased efficiency and productivity. This paper discusses the state-of-the-art of IoT, focusing on key technological drivers, potential applications, challenges, and future research areas. It also discusses different definitions of IoT from academic and industry perspectives and identifies major issues for future research.
IoT is defined as a "world-wide network of interconnected objects uniquely addressable, based on standard communication protocols." This implies a large number of possibly heterogeneous objects involved in the process. The main challenges in IoT include achieving full interoperability between interconnected devices, providing them with a high degree of smartness through adaptation and autonomous behavior, while ensuring trust, security, and privacy of users and their data. Additionally, IoT poses new problems related to the efficient utilization of resources in low-powered, resource-constrained objects.
Several industrial, standardization, and research bodies are currently involved in developing solutions to meet the technological requirements of IoT. The objective of this paper is to provide a comprehensive discussion on the current state of the art of IoT, with a focus on protocol, algorithm, and system design and development, as well as future research and technology trends.
Section 2 presents the vision of IoT. Section 3 discusses a generic layered architectural framework for IoT and various issues involved in different layers. Section 4 presents the key technologies involved in IoT. Section 5 presents some specific applications of IoT in various industry verticals. Section 6 identifies some of the challenges in deploying the concept of IoT in the real-world. Section 7 presents future research areas in the domain of IoT, and Section 8 concludes the paper.
The paper discusses various IoT visions, including the semantic perspective, the web of things, and the Internet perspective. It also discusses the architecture of IoT, which consists of several layers, from the field data acquisition layer at the bottom to the application layer at the top.
