A Fuzzy Grouping Method for Data Distribution Management
Chen Gen · Chinese Journal of Computers · 2005
An efficient DDM (Data Distribution Management) method——fuzzy grouping method is presented. In order to reduce the matching number and increase the data filtering rates, meanwhile to keep high and stable relevant data reception rates, this new method added two new techniques based on the fuzzy correlation space approach: fuzzy consistent relation based weight distribution and grid based preprocessing. Simulation results show that fuzzy grouping method not only keeps high and stable data filtering rates in different situation but also greatly reduces matching number compared with existing methods.
