Abstract
The current approach to DDM in HLA is of the use of overlapping regions to
find out which subscribers are interested in the data of which publishers.
The Grid-Based Approach aims to make data filtering even more precise, by
breaking up the routing space into cells. Using these cells, it will
determine which cell the attribute update of the publisher is in and the
subscribers that are in this cell, and will then multicast the information
to these subscribers.
