A Survey of State-of-the-art on Edge Computing: Theoretical Models, Technologies, Directions, and Development Paths

In order to describe the roadmap of current edge computing research activities, we first address a brief overview of the most advanced edge computing surveys published in the last six years. It is true that edge computing has been adaptively integrated into growing number of applications. Edge computing theory and technology will bring substantial innovation and incentive, as well as a large number of application scenarios in different fields, such as edge computing assisted smart city, Internet of Vehicles(IoV), Industrial Internet, and many other different fields. In the field of edge computing, however, it is actually lack of a comprehensive investigation of using the most advanced theoretical models, technologies, directions and development paths. To fill this gap, by identifying and classifying, we carry out an in-depth survey of the latest high-quality literatures related to the theoretical discoveries in edge computing(EC) and the fusion of EC and the frontiers of Information and Communication Technology (ICT). Finally, it is summarized several promising open issues, and also pointed forwards the directions of future research. We hope that this survey report will attract much more attention, stimulate fruitful discussions, and provide ideas and useful guidance for further research on the theoretical models, technologies, directions and development paths of edge computing.
