Adapting to Dynamic User Environments in Complex Event Processing System using Transitions

Complex Event Processing (CEP) system enables extraction of higher-level information from real-time data streams produced by distributed sources. However, these systems are subject to changes in the user environment e.g., density of sources, rate at which events occur and mobile sources. Therefore, it becomes difficult to satisfy stringent performance requirements posed in terms of Quality of Service (QoS) demands under such a dynamic environment.
