A mobile replicated database is comprised of several mobile and fixed servers and clients interconnected through a wireless network. In order to ensure data consistency in mobile replicated databases, several replication control protocols have been proposed. However, most of them reveal relevant limitations, such as: possessing a single failure point and flooding the network with messages exchange. In this paper we introduce a protocol which guarantees data consistency of replicated databases in mobile computing. The proposed approach is completely distributed, avoids the existence of a single failure point, uses a read-any/write-any replication scheme, increases data availability, and reduces the number of messages exchanged among the replicated servers. Furthermore, it allows the user to choose a transaction isolation level (degree in which the execution of a given transaction is isolated from all other concurrent transactions). Experimental results show the potential efficiency of the proposed approach.
