Summarisation for Mobile Databases
In mobile computing, issues such as limited resources, network capacities and organisational constraints may cause the complete replication of large databases on a mobile device to be infeasible. At the same time, some on-board storage of data is attractive as communication to the main database can be inconsistent. Thus, as the emphasis on application mobility increases, data summarisation offe...
متن کاملMobile P2P Databases
A mobile peer-to-peer (P2P) database is a complex spatial-temporal system, in which information is stored in the peers of a mobile P2P network. The mobile peers communicate with each other via short range wireless protocols, such as IEEE 802.11, Bluetooth, Zigbee, or Ultra Wide Band (UWB). These protocols provide broadband (typically tens of Mbps) but short-range (typically 10-100 meters) wirel...
متن کاملCoordinating Mobile Databases
We are interested in the development of a database management layer which is completely portable and, therefore, “pluggable” on top of multiple host platforms. This layer, so called Peer Database Management System (PDBMS), must be able to remotely connect with its database and to connect it with other peer databases. We realize mobility by storing PDBMS on a flash drive. We realize network inde...
متن کاملPlanned Disconnections for Mobile Databases
As mobility permeates todays computing environment, we envision application infrastructures that will increasingly use mobile technologies. Traditional database applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement in such an environment is to support frequent connection an...
متن کاملMultiversion Reconciliation for Mobile Databases
As mobile computing devices become more and more popular, mobile databases have started gaining popularity. An important feature of these database systems is their ability to allow optimistic replication of data by permitting disconnected mobile devices to perform local updates on replicated data. The fundamental problem in this approach is the reconciliation problem, i.e. the problem of serial...
