Method for trust collaborative services for maritime edge computing network

Abstract

The invention discloses a method for trust collaborative services for maritime edge computing network (TCSMEC). The method is based on a collaborative filtering idea. A network heartbeat information piggyback technology is adopted, fusing the node similarity relationship, the network behavior, the link feature and the neighbor similarity node to construct a local trust network, recommendation is carried out based on the service capability, the service quality, the load, the trust relationship between the nodes and other characteristics of the edge computing service nodes. a quartile method isadopted to filter service quality evaluation information to improve recommendation effectiveness. Self-adaptive edge computing service access and rapid resource fusion are realized through queue hierarchical control. Simulation experiments show that compared with ADOV and RandomWalk methods, the TCSMEC has the advantages that the service energy consumption, the load efficiency, the link transmission rate and the like are obviously dominated, and the TCSMEC can efficiently realize the marine edge computing trusted collaborative task migration service in a complex marine meteorological environment.

Description

technical field [0001] The invention relates to the field of maritime edge computing, in particular to a method for migrating trusted collaborative tasks of maritime edge computing. Background technique [0002] With the rapid development of technologies such as cloud computing, big data, and the Internet of Things and the popularization and application of mobile smart devices, applications with large traffic, large connections, and delay-sensitive applications such as the Internet of Things, multimedia, and instant messaging at sea have become the main business of maritime communication network traffic. , put forward higher requirements for the service capability of maritime communication business. However, the maritime wireless communication link covers a wide area, the environment is changeable, and the maritime communication nodes are faced with many resource constraints such as energy, computing, storage, and communication. It is difficult to guarantee the quality of se...

AI Technical Summary

Problems solved by technology

[0005] The main problem encountered in the construction of maritime edge computing networks is that the marine environment is extremely complex and changeable, most of them are uninhabited islands and reefs with extremely uneven distribution, resource constraints and difficult construction, etc. It is difficult to realize land-based networking with base stations as the core

At the same time, the computing, storage, energy, bandwidth and other resources of offshore nodes are relatively limited, and there may be broken links, single point failures, and excessive loads when implementing edge computing services
