Wireless and mobile communication is an important technology that improves user's daily life and facilitates the development of some new technology such as electronic commerce and mobile commerce. Replication is a fundamental technique for supporting concurrent work practices in mobile environments.

In return, they become far more efficient and available than traditional replication algorithms that keep all the replicas consistent, especially when the network and computers are unreliable.
