The increasing volume, diversity, and complexity of resources and data continues to raise challenges in the sharing and dissemination of information. Although publish-subscribe systems have improved the ability of users to exchange information, we argue ...

This poster presents Intelligent Traffic Light (ITL), which is a cyber physical system that combines information technology (e.g., real-time publish/subscribe semantics) and communications technology (e.g., mobility and wireless) with the transportation ...

In this paper, we aim at contributing to the current discussion of the architecture design of a Network of Information supporting a Data-Centric approach, we explore the ability to extend the "Publish and Subscribe"(Pub/Sub) service model to the ...

Message-oriented middleware (MOM) is increasingly used as enabling technology for modern event-driven applications typically based on publish/subscribe (pub/sub) communication [1]. Many of these applications are designed for maximum scalability and ...

In this paper we focus on providing reliability as a service guarantee to subscribers in an Event Based Middleware. We provide an additional level of granularity to subscribers by enabling them to specify individual reliability requirements on a per ...

Modern space systems such as satellites, human spacecraft, planetary probes and space robots are highly sensored and generate large amounts of data. For this data to be useful to humans monitoring these systems and to automated algorithms controlling ...

In this demo we show the current state of our client-side rule engine for the Web. The engine is accompanied by a rule language for event-condition-action expressions especially tailored to be run on JavaScript-enabled clients. Rules may contain complex ...

Complex middleware frameworks are made out of interacting components which may include bugs. These frameworks are often extended to provide additional features by third-party extensions that may not be completely trusted and, as a result, compromise the ...

In this paper we propose to demonstrate a logic-based and data-driven complex event processor. The event processor is called ETALIS (Event-driven Transaction Logic Inference System). ETALIS is based on decomposition of complex event patterns into ...

Event stream processing (ESP) has become increasingly important in modern applications, ranging from supply chain management to real-time intrusion detection. Existing ESP engines have focused on detecting temporal patterns from instantaneous events, ...

We note that over the past decade publish-subscribe systems have improved the ability of users to exchange information but we argue that these systems have been either restrictive or simplistic - relying on narrowly defined channels for data exchange. ...

The event-driven communication paradigm provides a number of advantages for building loosely coupled distributed systems. However, the loose coupling of components in such systems makes it hard for developers to estimate their behavior and performance ...

Event stream processing (ESP) [7][2][5][6] technologies enable enterprise applications such as algorithmic trading, RFID data processing, fraud detection and location-based services in telecommunications. The key applications of the ESP technologies ...

Traffic signals provide the key mechanism to regulate traffic, and promote safe and efficient traffic flow at intersections. However, incidents of red light running can compromise the safety of the system. These incidents stem mostly due to the well ...

The developments and successes of the Semantic Web research community in building standards and tools for semantic technologies such as formalized vocabularies/ontologies and declarative rules are opening novel research and application areas. One of ...

Emerging trends and challenges. The number and type of distributed systems that utilize publish/subscribe (pub/sub) technologies are growing due to the advantages of performance, cost, and scale compared with single computers [1, 2]. Examples of pub/sub ...

In this paper, we present a powerful logic-based approach for Complex Event Processing (CEP). The approach is founded on a logical transformation of event processing into logic programs. Many systems for event processing have ad-hoc semantics with ...

Reference architectures predefine a common frame of reference, which can be customised to obtain architectures for specific applications in a domain. Based on a general reference model, providing a common language and semantics to explain the important ...

The development and operation of modern IT infrastructures requires generally accepted standards. Many standardization efforts are currently ongoing within the service oriented and event processing community. Recently a new discipline entitled "Event-...

Researchers have been exploring various aspects of distributed event-based systems for distributed applications; namely protocols, semantics of events etc. However there has been little focus on QoS metrics that help determine whether such applications ...
