Abstract : Real-time collaborative editing systems are common in our everyday work life. They allow multiple authors to collaboratively write and review documents. Mobile devices are pervasive and therefore supporting collaborative editing applications becomes a natural need. In traditional real-time editing applications, a replication mechanism is required to offer support for concurrent editing while preserving consistency of the shared documents. Recently, a new class of replication mechanisms, named Commutative Replicated Data Types (CRDTs), was introduced for collaborative editing. They are expected to be substitutes of replication mechanisms in next generation collaborative editing systems. However, their suitability under mobile resources constraints such as limited computation and memory remains to be investigated. This paper presents an ongoing work in the evaluation of the suitability of CRDTs for real-time collaborative editing on mobile devices. Performance evaluations in terms of computation time and memory requirements for various CRDTs are presented. Additionally, it provides a comparison with traditional replication mechanisms.
