An efficient DDM (data distribution management) approach-fuzzy grouping mechanism was presented. In order to reduce the matching times and increase the data filtering rate, this new mechanism adopted two techniques based on the fuzzy correlation space approach: fuzzy consistent relation based weight distribution and grid based preprocessing. Simulation results indicate that: compared with existing approaches, fuzzy grouping mechanism not only keeps high and stable data filtering rates in different situations but also greatly reduces matching times.
