Abstract
A distributed event detection system for detecting a complex event by a distributed detection process, includes a plurality of broker nodes for routing events and a route node for distributing the complex event, wherein the route node comprises a detection formula decomposing unit which decomposes a complex event detection formula for detecting the complex event into a plurality of complex sub-event detection formulae; a sub-route node assignment unit which assigns a broker node as a sub-route node with respect to each of the complex sub-event detection formulae decomposed by the detection formula decomposing unit; and a complex event detecting unit which detects the complex event based on a complex sub-event detected by the sub-route node assigned by the sub-route node assignment unit.
