Enabling Technologies, Protocols, and Applications: A Detailed Survey on IOT

The Internet of things is used as a parasol catch word for combining and covering the major aspects related to the extension of the Internet and Web into the phenomenon, by means of vast positioning of spatially distributed devices that contains embedded identification, sensing and/or actuation capabilities. Internet of Things (IoT) consists of a large number of connected objects that are communicating with each other. To discuss the Internet of things in wider sense and precedence on protocols, technologies, and application along with related issues. The main factor IoT concept is the integration of different technologies. The IoT is empowered by the hottest developments in RFID, smart sensors, communication technologies, and Internet protocols. The primary hypothesis is to have smart sensor dealing directly to deliver a class of applications without any external or human participation. Recently development in the Internet and smartphone and machine-to-machine technologies can be considered the first phase of the IoT. In the platinum should continue to raise IoT is expected to be one of the main hubs between various technologies by connecting smart physical objects together and allow different applications in support of smart decision making. In this paper, we discuss IoT architecture and the technical aspect that relate to IoT. Then, give an overview of IoT technologies, protocols and applications and related issues with a comparison of other survey papers. The survey aims to help other researchers in delving into the details of such techniques by going through their classification and comparison. The classification has been done based on the inherent features of this authentication technique such as being distributed vs. centralized, flat vs. hierarchical, and more others.
