Cloud-Based Lightweight Collaborative Editing Algorithm for Mobile Devices

With the burgeoning of mobile devices, collaborative editing through mobile devices has become an alternative choice to traditional desktop PCs. However, mobile collaborative editing has to face some technical challenges. How to achieve an efficient mobile collaboration while maintaining the shared document copies consistency is one of the core issues in collaborative computing area. This paper proposes a cloud-based lightweight collaborative algorithm for mobile devices. Firstly, a cloud-based mobile collaborative editing framework is proposed for collaborating between cloud platform and mobile devices. Secondly, a collaborative editing task allocation model is constructed to assign editing operations for cloud platform and mobile devices. Thirdly, a cloud-based lightweight collaborative editing approach is presented to achieve the data synchronization and the consistency maintenance for the shared document copies. Finally, experiments evaluations prove the effectiveness of the proposed approach.
