Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0039] Such as figure 1 As shown, the present invention provides a D2D-based decentralized shared storage system and its control method. The control system includes: a data fragmentation module, which is used to perform bit operations on data, and divide the data according to the size of the data The above data is divided into several fragmented data; the data request module is used to obtain the fragmented data and send a data request to the dispatching center module; and transmit the fragmented data to the storage consensus domain module; the dispatching center module is used to process the desc...

Abstract

The invention discloses a D2D-based decentralized shared storage system and a control method thereof, and the system comprises a data fragmentation module which divides data into a plurality of piecesof fragmented data; The data request module is used for acquiring fragmented data and sending a data request to the scheduling center module; Transmitting the fragmented data to a storage consensus domain module; The dispatching center module is used for carrying out first-time analysis and verification on the data request sent by the data request module; Transmitting a data request to a storageconsensus domain module; The storage consensus domain module is used for carrying out second-time analysis and verification on the data request; Judging the type of the data request; Sending a judgment completion signal to the data request module; Receiving the fragmented data sent by the data request module; And querying, storing and backing up the fragmented data. The method has the advantages that the data is fragmented, dispersed and stored in the D2D user, the data dispersion of the user can be guaranteed and cannot be checked, so that the trust problem among the users is solved, and thebackup of user data and the traceability and restoration of the data are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of D2D communication, in particular to a D2D-based decentralized shared storage system and a control method thereof. Background technique [0002] D2D (Device-to-Device, D2D communication technology) is D2D communication based on cellular network, or Proximity Service (Proximity Service, ProSe), which means that user data can be directly transmitted between terminals without going through the network. Traditional wireless communication networks have high requirements for communication infrastructure, and damage to core network facilities or access network equipment may lead to the breakdown of the communication system. In the D2D communication mode, user data is directly transmitted between terminals, which avoids the transfer and transmission of user data through the network in cellular communication, resulting in link gain; secondly, resources between D2D users and between D2D and cells can be reus...
