Wireless networks are becoming popular in data communication and suitable for data sharing among users using multicast capability, but have hidden node problems. The optimistic consistency scheme has been established with respect to data consistency and availability in disconnected environment. This paper proposes a data coherency protocol for mobile devices. This protocol lessens data traffic in data collaboration using multicast communication feature and is capable of automatic recovery from unpredictable disconnection, such as hidden node problem, by data versioning using version vectors and update log management in an optimistic data consistency scheme. We evaluated efficiency of data sharing over multicast communication and the recovery cost from failure caused by hidden nodes, and confirmed the efficiency of the protocol.
