Opportunistic social network effective data transmission method based on node socialization

Abstract

The invention provides an opportunistic social network effective data transmission method based on node socialization, and the method comprises the steps: dividing nodes in a network into a pluralityof different communities, removing some low-efficiency nodes according to the attributes of an optimal relay node, and carrying out the community reduction; measuring the availability of the node by proposing concepts of sending trust, receiving trust, residual cache and activity index; in an opportunistic social network, if the nodes simultaneously satisfy these characteristics, determining a fact that the nodes are more likely to be optimal relay nodes. And the continuity, the stability and the high efficiency of the data transmission process can be maintained through the reduced high-efficiency community transmission data packet. Simulation results show that the packet delivery rate of the ETNS is % higher than that of an epidemic algorithm by 13%, and meanwhile, the ETNS has relativelylow transmission delay and routing overhead.

Description

technical field [0001] The invention belongs to the field of computer technology, in particular to an effective data transmission method of an opportunity social network based on node socialization. Background technique [0002] With the popularization of the Internet and the development of social informatization, information dissemination based on various online social platforms has become an extremely important means. Many social platforms, such as Facebook, Instagram, and Twitter, have sufficient capacity to support billions of users to participate in the information transmission process. Through online platforms, people can attract more people's attention by sharing interesting things in life. When users communicate and surf the Internet through mobile devices, they can post photos or videos anytime and anywhere. [0003] In social networks, the ability of the network to communicate at high speed is very important. Through the evaluation of human communication activit...

AI Technical Summary

Problems solved by technology

This type of community node is a node that is not efficient and requires a lot of resources for transmission, but its transmission performance is not ideal, so it is necessary to propose a method to reduce costs

Social network communications that transfer large amounts of data simultaneously can lead to excessive energy consumption, low transfer rates, and transfer delays
