Data-intensive real-time applications, such as transportation management, military surveillance, and network monitoring, need to handle massive amounts of stream data in a timely fashion. It is challenging to support real-time stream data services (RTSDS) due to stringent timing constraints, potentially unbounded continuous stream data, bursty stream data arrivals, and workload variations due to data value changes. This project will develop cost-effective methods and a runtime system for RTSDS. The project will systematically investigate methods and tools to support real-time continuous queries for RTSDS even in the presence of dynamic workloads. Specifically, the project will study a) real-time continuous query modeling, b) new performance metric design c) adaptive query scheduling design, d) tardiness control and load shedding, for both single node and clustered RTSDS. The project will also have prototype implementation and testbed evaluations. The results and findings of this project will advance and seamlessly integrate real-time computing and stream data management.Real-time stream data services (RTSDS) play an important role in many emerging application including intelligent transportation, green buildings, smart grid management, military surveillance, and network monitoring. Our everyday lives are highly dependent on these applications. RTSDS is a fundamental technology for developing critical data-intensive real-time applications with great socio-economic impacts. The project will develop the scientific foundations and associated engineering principles for building RTSDS. The project will provide excellent opportunities for undergraduate and graduate students to acquire hands-on experience as well as theoretical backgrounds in RTSDS. The PIs will work closely with students to carry out the research in this project. Through this project, the PIs will train students to become strong in both analytical and implementation skills, and help them solve challenging problems in RTSDS.

数据密集型的实时应用，如交通管理、军事监视和网络监控，需要及时处理大量的流数据。由于严格的时间约束、潜在的无界连续流数据、突发流数据到达以及由于数据值变化而引起的工作负载变化，支持实时流数据服务（RTSDS）是具有挑战性的。该项目将为RTSDS开发具有成本效益的方法和运行时系统。该项目将系统地研究方法和工具，以支持实时连续查询RTSDS，即使在动态工作负载的存在。具体来说，该项目将研究a）实时连续查询建模，B）新的性能指标设计，c）自适应查询调度设计，d）延迟控制和负载削减，为单节点和集群RTSDS。该项目还将进行原型实施和试验台评价。实时流数据服务（Real-time Stream Data Services，RTSDS）在智能交通、绿色建筑、智能电网管理、军事监视、网络监控等新兴应用中发挥着重要作用。我们的日常生活非常依赖这些应用程序。RTSDS是开发具有重大社会经济影响的关键数据密集型实时应用程序的基础技术。该项目将为建立RTSDS奠定科学基础和相关的工程原则。该项目将为本科生和研究生提供极好的机会，以获得实践经验以及RTSDS的理论背景。PI将与学生密切合作，开展本项目的研究。通过这个项目，PI将训练学生在分析和实施技能方面变得强大，并帮助他们解决RTSDS中具有挑战性的问题。
