Paradise and Direct Broadcast Satellite: A Solution to Battlefield Data Dissemination for the 21st Century

摘要

This paper describes results from research under the Battlefield Aware Data Distribution (BADD) project. The goal of this research is to find new approaches to intelligent data distribution from distributed servers to roaming clients whose needs evolve with time. The primary focus of this report is on the part of the problem associated with the development of satellite-based information dissemination network infrastructure and smart push and filtering techniques. Research focused on possible ways to merge queries based on more abstract ideas, such as through generalization in a concept hierarchy. A number of issues in client cache management were also explored.
