Study of fog computing structure

The future Internet structure will be based on cloud computing. With the increase of the mobile traffic, the transmission of an huge amount of data to the cloud was not only a difficult task for the communication channel bandwidth, but also caused delays in transmission and a decline in the quality of services for the end user. With the growth of the role of mobile traffic, the support of mobility and geometric distribution is no less important. For this reason, the emergence of cloud computing as a comprehensive approach for the centralized storage, retrieval and management of information, the successful integration of cloud computing and mobile applications, is an important task. To solve such problems, Cisco introduced a concept of fog computing, designed for local processing of some tasks on fog devices. The fog layer consists of geo-allocated servers that are deployed on the network periphery. Each fog server is a lightweight version of the cloud server, and is equipped with a large data warehouse and the ability to compute and wireless transmission. In this paper, the authors emulated the operation of network nodes under fog computing conditions.
