Efficient Synchronization of Multiple Databases over Broadcast Networks [chapter]

Muhammad Muhammad, Stefan Erl, Matteo Berioli
2013 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
This work deals with the problem of synchronizing multiple distributed databases over a broadcast network, such as satellite networks.  ...  Compared to point-to-point and traditional broadcasting synchronization methods, the algorithm implementing network coding allows reaching the lower-bound for the number of packets exchange.  ...  These distributed databases are physically spread over a computer network of multiple nodes, where any node can update its database at any time.  ...

Mobile ad-hoc network data communication in large geographic areas

L.D. Fife, Le Gruenwald
2006 IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006.  
In support of the data communication needs existing in these networks, a database is utilized for data broadcast and data query.  ...  A Mobile Ad-Hoc Network (MANET) is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks.  ...  As the likelihood of a client hearing more than a single data broadcast is very small, the clients will not hear multiple static portions of broadcasts.  ...

Caching and Replication in Mobile Data Management

Evaggelia Pitoura, Panos K. Chrysanthis
2007 IEEE Data Engineering Bulletin  
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  ...  We consider two antagonistic criteria, that of ensuring quality of data in terms of consistency and coherency and that of achieving quality of service in terms of response time and availability.  ...  With multiversion broadcast [20, 18] , multiple versions of each item are broadcast, so that client transactions always read a consistent database snapshot.  ...
