Lightweight asynchronous mobile collaborative editing method based on CRDT

Abstract

According to the technical scheme adopted by the invention, a lightweight asynchronous mobile collaborative editing method based on CRDT is characterized by comprising the following steps of: A, initializing mobile equipment, including initializing an initial shared document copy state, emptying an operation log, and initializing a synchronous variable to be 0; B, generating and integrating local operation, wherein the mobile equipment adds the local operation into a corresponding operation log, and then an integration function of the local operation is called to execute the local operation; C, synchronization with other mobile equipment: sending the local operation to be synchronized to the other mobile equipment, and receiving the remote operation of the other equipment; and D, integrating remote operation, including calling an integration function of the remote operation, and executing the received remote operation. According to the invention, a collaborative editing service with good interactivity and responsiveness is provided for mobile users.

Description

technical field [0001] The invention belongs to the technical field of collaborative computing and mobile computing, in particular to a lightweight asynchronous mobile collaborative editing method based on CRDT (CRDT, Commutative Replicated Data Type). Background technique [0002] In recent years, with the popularization of wireless networks and the rapid development of mobile devices, smart mobile terminals have become popular mobile computing platforms, supporting various mobile applications such as e-commerce, social media, mobile finance, and mobile healthcare. Mobile collaborative editing based on smart terminals allows geographically dispersed collaborative workers to collaboratively edit / design shared objects through the mobile Internet, effectively exerting group wisdom, and improving the quality and efficiency of collaborative product design. It is a collaborative computing / computer-supported collaborative work (CSCW , one of the core contents of the Computer Suppo...

AI Technical Summary

Problems solved by technology

However, there is little research on CRDT-based mobile collaborative applications

The main reason is that mobile collaborative editing shows many new features in terms of architecture, user scale, power of mobile devices, storage and computing resources, etc.: (1) In terms of architecture, mobile users need to cooperate with each other and share data and (2) In terms of user scale, mobile users have a large scale and wide geographical distribution, and can join or leave collaborative sessions anytime and anywhere; (3) In terms of mobile devices, resources such as power supply, storage, computing, and network bandwidth of mobile devices are closely related to There has always been a big gap compared with traditional non-mobile devices; (4) In terms of responsiveness and delay, it is necessary to provide mobile users with low-latency, high-response collaborative services
