Summary: | Civil engineers have introduced sophisticated sensing and control systems to better operate infrastructure systems, resulting in what are termed advanced infrastructure systems (AISs). Past AIS research has largely focused upon the sensors needed to collect data, as well as applications using this data to derive information to drive management/control decisions. Of equal importance to AIS success is the availability of an effective data delivery mechanism to ensure that data are effectively provided to applications. This research examined the challenge of data delivery in AISs. Following an analysis of AIS characteristics and a review of the state-of-the-practice in AIS data delivery, the paper presents a peer-to-peer-based publish/subscribe architecture developed by the research team to meet AIS data delivery requirements. Finally, a case study is presented in which the architecture is tailored for a vehicle-infrastructure integration AIS implementation. Simulation results of the implementation reveal that the proposed architecture provides significant scalability benefits, as compared to traditional data delivery approaches, providing up to a 50% reduction in message transmissions without increasing delivery times to unacceptable levels. |
