The C3PO project promotes the development of a new kind of spontaneous and ephemeral social networks dedicated to happenings. They rely both on opportunistic communication networks formed dynamically by mobile devices, and on an event-based ...

Distributed Event-Based Systems (DEBS) provide a versatile solution for asynchronously exchanging data in a distributed system, loosely-coupled in space and time. In this work, the software architecture of a DEBS is composed of an overlay network of ...

We describe an approach for a custom complex event processing engine using Message Passing Interface (MPI) in C++ programming language. Our approach utilizes a multi-processor infrastructure and distributes its load on multiple processes, expecting each ...

Traffic monitoring is an important stream processing application, which is highly dynamic and requires aggregation of spatially collocated data. Inspired by this, the DEBS 2015 Grand Challenge uses publicly available taxi transportation information to ...

In this paper, we provide a solution for the ACM DEBS Grand Challenge 2015 (GC 2015) that deals with the analysis of taxi trips in New York based on the data stream management framework Odysseus [1].

The DEBS 2015 Grand Challenge [2] defined a stream-processing problem on data collected through the FOILing NYC's Taxi Trip Data project [1]. These data include itinerary information on all rides of over 10,000 taxis in a wide area of 150kmx150km around ...

Spring XD is a unified, distributed and extensible system for data ingestion, real time analytics, batch processing, and data export. The objective of Spring XD is to simplify the development and deployment of streaming and batching data applications. ...

This paper proposes a model inference framework for production systems distributed over multiple devices exchanging thousands of events. Building models for such systems and keeping them up to date is time consuming and expensive, thus not adequately ...

Systems such as social networks, search engines or trading platforms operate geographically distant sites that continuously generate streams of events at high-rate. Such events can be access logs to web servers, feeds of messages from participants of a ...

Publish/subscribe communication is increasingly often the basis for distributed, event-based, and loosely-coupled applications. With this communication paradigm, application components communicate indirectly by publishing notifications and by ...

Realizing a communication middleware in a software-defined network can leverage significant performance gains in terms of latency, throughput and bandwidth efficiency. For example, filtering operations in an event-based middleware can be performed ...

Complex event processing (CEP) middleware systems are increasingly adopted to implement distributed applications: they not only dispatch events across components, but also embed part of the application logic into declarative rules that detect situations ...

Experiments in high-energy physics (HEP) and related fields often impose constraints and challenges on data acquisition systems. As a result, these systems are implemented as unique mixtures of custom and commercial-off-the-shelf electronics (COTS), ...

QoS support is important for a large-scale content-based publish/subscribe (pub/sub) system to provide guaranteed service for clients with high QoS requirements. So far, great efforts have been dedicated to integrating QoS support into pub/sub systems. ...
