The Internet of things—a survey of topics and trends

Abstract The Internet of Things is a paradigm where every-day objects can be equipped with identifying, sensing, net-working and processing capabilities that will allow them to communicate with one another and with other devices and services over the Internet to accomplish some objective. Ulti-mately, IoT devices will be ubiquitous, context-aware and will enable ambient intelligence. This article reports on the current state of research on the Internet of Things by examining the literature, identifying current trends, describing challenges that threaten IoT diffusion, presenting open research questions and future directions and compiling a comprehensive refer-ence list to assist researchers
