Abstract: This paper described the alarm correlation in communication networks based on data mining. A direct applicalion of sequential algorithms to distributed databases is not effective,because it requires a large amount of communicalion overhead. An efficient algorithm-EDMA was proposed. It minimized the number of candidate sets and exchanged messages by local and global pruning. In local sites, it runs the application based on the improved algorithm-CMatrix,which is used to calculate local support counts. Our solution also reduced the size of average transactions and datasets that leads to reduction of scan time. I}he performance study shows that EDMA has superior running efficiency, lower communication cost and stronger scalability than direct application of a sequential algorithm in distributed databases.
