Survey of Standardized Protocols for the Internet of Things

Internet of Things is a growing technology, developing in multiple fields, from smart homes to health and industries. From a technological perspective, it enables the development of new protocols and scenarios, since the standard network protocol suite cannot face the growing number of connected devices and data transmitted. This paper aims to present several standardized protocols, at different networking levels, developed especially for embedded devices with low memory, low processing power and low data rate. We also propose a smart home scenario that uses only standardized IoT protocols.

I. Introduction

Recently, the Internet of Things (IoT) has become an important research field. It can be described as a communication system where any device can be connected to the Internet and be able to identify itself to other objects. It can be applied in different domains, from personal use, such as smart homes or wearable devices to fields such as urban environment monitoring, health care, industrial automation or emergencies.
