Edge Computing: A Systematic Mapping Study

With the rapid development of 5G and artificial intelligence (AI) technology, more and more intelligent devices are connected to the Internet, and the demand for computing services is also increasing. The traditional combination of cloud computing and the Internet of Things (IoT) has gradually revealed some drawbacks, such as transmission delay, greatly reduced transmission rate and network bandwidth pressure. Edge computing is a new computing paradigm. It puts the service near the physical edge of the end users. Due to its close proximity, dense distribution and low latency, edge computing can effectively reduce latency, improve transmission speed and relieve bandwidth pressure. At present, there are more and more researches on edge computing. It is necessary to discuss edge computing in general. The system mapping study uses the visualization method to summarize a specific field. This paper aims to introduce the development of edge computation in detail by means of a systematic mapping study. Firstly, we introduce the definition, characteristics and classification of edge computing, and then introduces the research methods of system mapping study. Finally, the research results of edge computing are obtained, including the publication trends of edge computing papers, the focuses of edge computing research and industrial applications.
