In modern advanced emergency management systems many solutions for decision support have been provided as attempts to support humans to take important decisions for the critical situations recovery. The critical situation detection is a complex procedure that involves both human and machine activities and leads to take a decision for the management and situation recovery. This paper presents an...

Recently the rapid development of Internet of Thing (IoT) brings new opportunity to Intelligent Transportation System (ITS). The key problem is how to process the huge events generated by IoT to support ITS. In this paper a proactive complex event processing method is proposed for congestion control in ITS. Based on complex event processing, this method predicts the traffic flow using a multi-l...

Recent research [34] shows that, provided a careful design, complex event processing (CEP) on top of a modern DBMS can compete in many cases with specialized DSMS which have been considered superior for a long time [8]. There are mainly two reasons why building complex event processing on top of an existing DBMS is desirable. First event processing profits form sophisticated techniques and algo...

Complex event processing has been widely used in many modern applications. A key aspect of complex event processing is to extract patterns from event streams to make informed decisions in real-time. However, network latencies and machine failures may cause events to arrive out-of-order at the event processing engine. To address the problem, a number of disordered event processing techniques are...

Modern scientific applications of sensor networks are driving the development of technologies to make heterogeneous sensor networks easier to deploy, program and use in multiple application contexts. One key requirement, addressed by this work, is the need for methods to detect events in real time that arise from complex correlations of measurements made by independent sensing devices. Because ...

State-of-the-art interoperability between heterogeneous systems on a technical level builds on services oriented architectures (SOA) for a given problem space. Semantics can be introduced by the use of descriptive languages and reasoning algorithms, usually implemented within a message-based enterprise service bus (ESB), the messages triggering service invocation and consumption. Complex event ...

Complex (or Composite) event processing systems have become more popular in a number of areas. Non-deterministic finite automata (NFA) are frequently used to evaluate CEP queries. However, it is complex or difficult to use the traditional NFA-based method to process patterns with conjunction and negation. In this paper, we proposed a new CEP system LogCEP using pushdown automaton to support eff...

Computing offloading is a promising technique for Internet of Things (IoT) to handle complex IoT events processing, e.g., voice recognition. Existing work mainly focuses on offloading in mobile networks, while little addresses the problems of heterogeneity and quality of experience (QoE) on resource constrained devices in edge networks. In this paper, we present a framework of QoE-aware edge co...

Complex Event Processing (CEP) is emerging as a new paradigm for continuous processing of streaming data in order to detect relevant information and provide support for timely reactions. The main role of a CEP engine is to detect the occurrence of event patterns on the incoming streaming data. However, the problem of discovering the event patterns, although strongly related to the data mining f...

Kontextbewusste Systeme bieten die Möglichkeit, dass Anwendungen ihr Verhalten ohne die aktive Einflussnahme von Anwendern selbstständig an vorherrschende Situationen anpassen. Dazu erfassen sie Kontextdaten, die verarbeitet und zur Steuerung der Anwendung verwendet werden. Aus diesem Grund wurden bereits Toolkits, Frameworks und Ansätze entwickelt, die eine einfache Entwicklung von kontextbewu...
