A survey: Internet of Things (IOT) technologies, applications and challenges

摘要

The main aim of this paper is to discuss the Internet of things in wider sense and prominence on protocols, technologies and application along 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. Primary hypothesis is to have smart sensor dealing directly to deliver a class of applications without any external or human participation. Recently development in Internet and smart phone and machine-to-machine M2M technologies can be consider first phase of the IoT. In the coming years IoT is expected to be one of the main hub 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 technical aspect that relate to IoT. Then, give over view about IoT technologies, protocols and applications and related issues with comparison of other survey papers. Our main aim to provide a framework to researcher and application developer that how different protocols works, over view of some key issues of IoT and the relation between IoT and other embryonic technologies including big data analytics and cloud computing.
