A hybrid replication strategy for mobile environments

The exponential increase in the smart phones has considerably increased the access to data services in mobile environments. As the mobile devices are prone to frequent disconnections, mobility issues, battery consumption etc, successful execution of the data services may not always be guaranteed. Replicating the data at several places provides the fault tolerance for the smart database applications. Synchronous replication may not be efficient to implement in mobile environments as the mobile hosts may be disconnected thereby leading to starvation. However to maintain the data consistent, synchronous replication strategy is to be adopted at fixed host. This paper presents a hybrid replication strategy in mobile environments which is realized by the mobile middleware.
