Abstract:
This work presents middleware to support network ready applications that enhance Situational Awareness (SA) on rotorcraft operations. SA of pilots, command and control teams and other participants collaborating in missions, is critical for rotorcraft operational performance, mission success, safety and survivability. Applications and systems that aim to enhance SA impose requirements of real-time communication and processing of data streams with high throughput and low latency. The presented middleware provides capabilities such as real-time data-centric publish subscribe communication with Quality of Service (QoS) contracts, Semantic Interoperability, and Distributed Complex Event Processing for real-time detection of situations. An illustrative Situation of Interest (SoI) is presented, based on a realistic scenario of helicopter rescue missions for offshore drilling. Simulation results are presented that compare different event processing distribution models and abstraction levels, regarding their impact on performance and scalability.
