摘要：Transaction management in wireless environment poses challenging issues in preserving data consistency and fault tolerance. As the mobile databases are prone to frequent disconnections, bandwidth limitations, mobility, etc. efficient execution of the transaction may not always be guaranteed. Replicating data at several sites is a powerful mechanism which not only increases performance but also provides fault tolerance for demanding database applications. However the major concern is to keep the replicated copies always consistent. In this paper various replication techniques and their applicability in the mobile environments are presented. Based on the requirements of the services provider and the type of execution model used, one of the replication strategies may be implemented.
