A DATA REPLICATION FOR MOBILE ENVIRONMENT

Karol Matiaško - Michal Zábovský

   Distributed database systems and distributed database management systems have been developed in response to trend of distributed computation. In distributed models of computations several sites are connected via a communications network. However, the need for mobile access to large databases leads to problems with mobile computers connectivity. Mobile computers often suffer from limited connectivity or lack of network access. Existing replicated databases are not well suited for mobile scenarios as well as algorithms used for data replication, in spite of fact that it is the most desirable environment. In the following paper we introduce algorithm for adaptive data replication including mobile computers connected by wireless network based on IEEE~802.11.

Keywords: distributed database systems, distributed database management systems, wireless networks, data replication
