Mobile data management has been an active area of research for the past fifteen years. Besides dealing with mobility itself, issues central in data management for mobile computing include low bandwidth, intermittent network connectivity and scarcity of resources with emphasis on power management. In this article, we focus on how caching and replication in mobile data management address these challenges. We consider two antagonistic criteria, that of ensuring quality of data in terms of

In general, one can distinguish between single-hop and multi-hop underlying infrastructures. In singlehop infrastructures, each mobile device communicates with a stationary host, which corresponds to its point
