Investigating the structure and challenges of the Internet of Things

Advances in wireless networking and communications technologies have led to the emergence of ‎Internet-related innovations known as the Internet of Things.‎The Internet of Things is defined as a pattern in which objects equipped with sensors and processors communicate with each other to pursue a meaningful goal.The IoT is able to integrate and transparently integrate a large number of heterogeneous and ‎diverse end systems by providing free access to select subset of data to improve a range of digital ‎services.In this paper, we survey protocols, and applications in this new emerging area ,then ‎analyze the challenges of the IoT
