The rapid growth of information and communication technology has led to the appearance of new phenomena in this area every day. One of these phenomena is the Internet of Things (IoT) technology, which aims to create a comfortable life in the form of a smart life. The Internet of things is a new technology used to connect things to each other over the Internet, the aim is to measure and control remotely an objects. The definition of IoT is that they are referred to as a set of things that have a digital identity and users can manage and organize these things using devices such as computers and smartphones and their applications and these things are capable of communicating with users and even with each other. The process of sending data on the Internet of Things does not require things to interact, and the data is sent automatically and based on the initial settings that are made on the hardware. Meanwhile, communication protocols play an important role. Choosing an appropriate communication protocol based on the needs and conditions of the environment is one of the most important issues in the Internet of Things.×In this paper, various communication protocols of the IoT such as 6LowPAN, NFC, BLE, Z-Wave, ZigBee, SIGFOX, Cellular are introduced and compared with each other in the Internet of Things. The goal of this comparison is to provide guidance to researchers who can select the appropriate protocol for different applications.
