| Abstract(in English) | publish/subscribe system captures the dynamic aspect of the specified information by notifying users of interesting events as soon as possible. Generally the rate of event arriving is time varying and unpredictable. It is very possible that no event arrives in an unit time and multiple events arrive in another unit time. When multiple events arrive at same time, the average response time of events filtering depends on the sequence of filtering events which have different workloads. In this paper, we first propose an event filtering algorithm with multiple inputs (multiple events) based on R-tree. With information of relative workload of each event, event by event filtering can be executed with short-job first policy which improves average response time of multiple jobs. Further a self-adaptive model is proposed and evaluated to filter set of events with different sizes on dynamically changed index. |
