Abstract

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. Keywords: public security, situation awareness, complex event processing, service oriented architecture, information fusion, smart sensors. 1 Introduction SERKET [1] stands for SEcuRity KEeps Threats away and its field of application is the security of public events and places. Its main objective is the development of a software system to provide support to the security and surveillance personnel avoiding the so-called cognitive overload problem. Moreover, the system is intended to be open, flexible and scalable at a low cost. In the SERKET security system, the intelligence resides in both software and security personnel. By means of the on-line analysis and fusion of complementary, as well as redundant, information coming from different sources – from sensors to
