Internet of Things: An Overview of Architecture, Models, Technologies, Protocols and Applications

Abstract

The Internet has established itself as a network and international communication medium, thus allowing people, computers and machines to communicate. The reduction in costs and size of interfaces that access the Internet allowed common devices (e.g. appliances, air conditioners, alarm systems and lighting) the access to a wide network. In a short time, the Internet of Things emerged, allowing the connection of an increasing number of intelligent devices from diverse fields of the economy. The growing application of IoT must be well understood, due to its potential to increase and use data in real-time, and the abundance of information available from sensors. Within this context, this work contributes with an updated overview of this new network environment in relation to its architecture, models, technologies, protocols and applications.
