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 its control method, including a data fragmentation module, which divides data into several fragmented data; a data request module, which obtains fragmented data and sends data to a dispatching center module request; and transmit fragmented data to the storage consensus domain module; the scheduling center module performs the first parsing and verification of the data request sent by the data request module; and transmits the data request to the storage consensus domain module; the storage consensus domain module performs data Requesting a second parsing and verification; judging the type of the data request; sending a signal of completion of judgment to the data request module; receiving the fragmented data sent by the data requesting module; querying, storing and backing up the fragmented data. The advantage is that by fragmenting the data and storing it in D2D users, it can ensure that the user's data is scattered and cannot be viewed, thereby solving the trust problem between users, and ensuring the backup and retroactive restoration of user data.

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...
