Elastic Infrastructure to Support Computing Clouds for Large-scale Cyber-Physical Systems

Large-scale cyber-physical systems (CPS) in mission-critical areas such as transportation, health care, energy, agriculture, defense, homeland security, and manufacturing, are becoming increasingly interconnected and interdependent. These types of CPS are unique in their need to combine rigorous control over timing and physical properties, as well as functional ones, while operating dynamically, reliably and affordably over significant scales of distribution, resource consumption, and utilization.

Real-time Sensor Data Analysis Processing of a Soccer Game Using OMG DDS Publish/Subscribe Middleware

This paper describes a real-time event-based system to distribute and analyze high-velocity sensor data collected from a soccer game case study used in the DEBS 2013 Grand Challenge. Our approach uses the OMG Data Distribution Service (DDS) for data dissemination and we combine it with algorithms to provide the necessary real-time analytics. We implemented the system using the Real-Time Innovations (RTI) ConnextTMDDS implementation, which provides a novel platform for Quality-of-Service (QoS)-aware distribution of data and real-time event processing.

A QoS Policy Configuration Modeling Language for Publish/Subscribe Middleware Platforms

ABSTRACT: Publish/subscribe (pub/sub) middleware platforms for event- based distributed systems often provide many configurable policies that affect end-to-end quality of service (QoS). Although the flexibility and functionality of pub/sub middle- ware platforms has matured, configuring their QoS policies in semantically compatible ways has become more complex.

Evaluating the Performance of Publish/Subscribe Platforms for Information Management in Distributed Real-time and Embedded Systems

Abstract: Recent trends in distributed real-time and embed- ded (DRE) systems motivate the development of infor- mation management capabilities that ensure the right information is delivered to the right place at the right time to satisfy quality of service (QoS) requirements in heterogeneous environments.
