Unified management of heterogeneous sensors for complex event processing

摘要

The turn of phrase that best summarizes SERKET's main goal is to provide security personnel with the right information at the right time. For this aim, the SERKET security system incorporates mechanisms to collect, fuse, filter and aggregate information coming from heterogeneous event sources and sensors. This Complex Event Processing is performed to improve the global situation awareness and the management of threats. Additionally, the system is intended to be as open, flexible and scalable as possible at a low cost. In this paper, the mechanisms by means of which scalability and flexibility features are achieved in the particular issue of sensors management are shown. Moreover, instead of simply homogenizing basic events and delegating their processing to higher levels of the system, it builds, as far as possible, a picture of the local situation. Therefore, the traffic to the rest of the system can be reduced since this local situation picture is transferred instead of many events that are too basic.
