In this paper we describe an architecture that provides for automating and monitoring the flow of control and document over the Internet among different organizations, thereby creating a platform necessary to describe higher order processes involving several organizations and companies. The higher order process is designed through a graphical user interface and is executed through cooperating agents...
Complex event processing (CEP) is an essential functionality for cross-reality environments. Through CEP, we can turn raw sensor data generated in the real world into more meaningful information that has some significance for the virtual world. In this article, the authors present DejaVu, a general-purpose event processing system built at ETH Zurich. SmartRFLib, a cross-reality application, builds...
Overload management has been an important problem for large-scale dynamic systems. In this paper, we study this problem in the context of our Borealis distributed stream processing system. We show that server nodes must coordinate in their load shedding decisions to achieve global control on output quality. We describe a distributed load shedding approach which provides this coordination by upstream...
