Replication and mobility
B. R. Badrinath, Tomasz Imieliński · 2003
Mobility of users and services and its impact on data replication and migration will be one of the main technical problems to be resolved. In fact, the authors view mobility as probably the most challenging new issue facing distributed systems of the future. The distinct new element which mobility brings into the issues of data replication is system's uncertainty about its own state (meaning primarily location). Thus the cost of communication between two mobile users is dependent not only on the distance between them but also on the cost of search necessary to determine the exact value of location. The authors address some of the questions, by proposing an adaptive replication scheme for mobile data.>
