Abstract
Collaborative editors are one of the most popular collaborative tools. They are being widely used thanks to the success of data sharing platforms where in most of the cases, data is shared with the intent to be edited simultaneously by many users who are distributed and dispersed across the globe. Keeping shared data synchronized is resource-intensive. With the emergence of collaborative editors over mobile devices, the challenges to meet increasing communication and computation are more and more noticeable. Indeed, the centralized cloud based architecture incurs high delays which prevents users from seeing shared data updates in real-time fashion. In this paper, we give an overview on existing cloud-based works and propose a new edge-based architecture for collaborative editors. Mobiles that are managed by the same edge are cloned to offload resource intensive tasks to the edge node, whereas only lightweight edition components are handled locally. This provides a more effective solution to manage concurrency and collaboration on mobile devices.
