Problems solved by technology

[0011] In the integrated system of blockchain and fog computing, whether the PoW problem can be successfully solved directly determines whether the MUB can obtain the final income. However, due to the limitation of the device's own performance, it is impractical to solve the PoW problem directly on the mobile terminal.

Embodiment Construction

[0093] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0094] 1 system model

[0095] The distributed fog service structure that integrates blockchain and fog computing systems is as follows: figure 1 As shown, the fog server can be deployed not only on base stations, but also on access terminals such as smart vehicles. According to the service capabilities provided by fog servers and the mobility of fog servers, fog nodes are divided into three categories: base station-based fog nodes (BN), fixed-location fog nodes (FN) and mobile fog nodes. Server MN (Moving fog Node). The base station fog server refers to the deployment of multiple fog servers with fog computing capabilities in the base station to provide computing, storage and other services for network access users. At the same time, the fog server can also be deployed on some devices with fixed geographical locations, such as RSU (R...

Abstract

The invention discloses an optimization task unloading method based on network time delay and resource management. The method comprises the steps that an optimization unloading PoW problem is studiedin a fusion blockchain and fog computing system based on node remaining resources and network time delay; in a network scene formed by a base station fog node, a fixed position fog node and a mobile fog node, the total duration required for unloading the PoW problem to various types of fog nodes is analyzed; the expenditure of the MUB is analyzed based on the remaining computing resources, storageresources and power resources of the network node and the social relationship between the nodes; an optimization task unloading scheme is provided based on node residual resources and network time delay, a mathematical optimization model is constructed by taking maximization of MUB income as a target, and the optimization model is solved by using an SA algorithm and a game theory; and finally, the superiority of the scheme is proved through analog simulation analysis. An intelligent task unloading mode of introducing artificial intelligence into the system is considered in future work.

Description

technical field [0001] The invention belongs to the field of communication technology, and relates to an optimization task unloading method based on network delay and resource management, in particular, to an optimization task unloading method based on network delay and resource management in a fusion block chain and fog computing system method. Background technique [0002] The basic idea of ​​fog computing technology is to sink the network functions provided by cloud servers to the edge of the network. Since fog servers are deployed closer to network users, compared with cloud computing, fog computing can effectively reduce data transmission delay. In addition, the distributed processing method adopted by fog computing can effectively alleviate the network congestion caused by the influx of large amounts of data into the cloud. Because the advantages of fog computing can meet the needs of future network applications, it has received extensive attention. [0003] Addition...
