The event matching algorithm, which checks the events against all the subscriptions, is a fundamental component of large-scale content-based publish/subscribe systems, and it is the key issue for improving the efficiency of the entire system. To meet the increasing efficiency requirements of real-time publish/subscribe systems, an event matching algorithm named PADEM (Pairwise Attribute Division based...
A novel algorithm for event matching of publish /subscribe systems is presented. To use the filtering abilities of attribute names and values synthetically, a double-deck tree structure is proposed. For the first deck, the proposed algorithm builds a tree structure by using the attribute names. All subscriptions are partitioned into the nodes of the first deck tree according to the attribute contained...
