One key challenge for the IoT is to manage huge amount of sensing data generated from different sources like smart devices etc. Without effective environment and a scalable architecture in place, it will be extremely difficult to handle or plan of IoT .This paper addresses the Internet of Things with focus on architecture and basic elements of IoT. The IoT is enabled by the latest developments in RFID, smart sensors, communication technologies, and Internet protocols. This paper begins by an overview and key element of IoT. Then, we give some technical detail of IoT architecture along with different layered architecture of IoT.We also provide an overview of some of the key IoT challenges presented in the current era. Keywords— RFID, IoT(Internet of Thing), EPC, NFC I. INTRODUCTION An increasing number of physical objects are being connected to the Internet at high rate realizing the idea of the Internet of Things (IoT). An internet has allowed an explosive growth of information exchange among these physical objects. With the start of sensing technology, the number of smart object including sensors, mobile phones, RF identifications (RFIDs), and smart grids has grown very fast in current year. A basic example of such objects are smart cities, smart homes, smart cars, and other smart spaces such as malls, workplaces, hotels, schools, and much More .The IoT enables smart device to see, hear, think and perform task by exchanging information and coordinate among them. The IoT transforms these objects from being none smart to smart by exploiting its fundamental technologies such as ubiquitous and invasive computing, embedded devices, communication technologies, sensor networks, Internet protocols and applications. Fig1. The overall picture of IoT Fig. 1 illustrates the overall concept of the IoT, in which every domain specific application is interacting with domain independent services, but in each area sensors and actuators commune straight by each other. The IoT is covering all significant home and business application, to contribute to the excellence of life and to raise the world’s economy. For example, smart-homes will enable their residents to automatically open the gate when entering home, make a coffee, make climate control systems, music player and other appliances. In order to realize this potential growth, emerging technologies and innovations, and service. II. IOT ARCHITECTURE Billions or trillions of heterogeneous objects are connecting through IoT. So there is a serious need for an ecosystem and a flexible layered architecture. The ever increasing number of proposed architectures has not yet converged to a reference model [12]. Based on the analysis of the needs of researchers and industry to try to design a common architecture like IoT-A [12 ]. Start from the group of architecture the first architecture is based on 3-
