Replicating databases over several servers is an efficient strategy to improve data availability and to increase transaction throughput rate. However, due to inherent limitations of mobile and other loosely-coupled environments, the replica control protocols responsible for ensuring replicated database consistency should be revisited. This paper proposes a new replica control protocol which guarantees the consistency of replicated databases in a mobile computing environment. The key benefit of the proposed protocol is to ensure consistency by means of the notion of transaction isolation levels without the use of a locking mechanism. Thus, a user may trade the degree of replica consistency for a potential increase in data availability and transaction through-put rate. The proposed protocol uses a read-any/write-any approach and reduces the number of messages exchanged among the replicated servers. Experimental results show the potential efficiency of the proposed approach.
