Edge Computing for Internet of Things: A Survey

The Internet of Things (IoT) is integrating the physical world with the information world. As more and more sensor devices are deployed in the IoT, IoT faces several challenges, such as transmission delay, data storage redundancy, and computing delay. The emergence of edge computing can address these challenges possibly. In this paper, we present an in-depth survey of the integration of edge computing and IoT. First, we briefly introduce the architecture of IoT and discuss a few challenges of IoT. Next, we give an overview of edge computing. We focus on the convergence of edge computing and IoT, and discuss the new architecture and advantages of EIoT. Finally, we summarize the applications of EIoT.
