Many of the services presumed to be vital in a mobile, tactical network can take advantage of a distributed database system with effective data dissemination. The use of a database system will improve the utilization of the communications resources and enable meeting more users' information demands. We will here describe three services that would benefit from a distributed database system; a command and control service, a service for soldier status information, and a service for video distribution. In this report we present two possible solutions for distributed databases in mobile, wireless ad-hoc networks. One design utilizes caching of requested data along the transmission path and the other pre-emptively disseminates data to the units where it's in highest demand. Furthermore, we describe two reference designs; one where no data is transmitted unless a specific request from a unit has occurred and one with total data dissemination, i.e. all data is relayed to all units. Through analyzing these designs for the chosen services, we determine that it is difficult to find a distributed database design that is suitable for all services. The use of a hybrid solution that uses different designs for different services hence appears to be best choice.
