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. Optimistic replication algorithms allow replica contents to become stale but in a controlled way. 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.
