Mosse-WuTime-critical applications in embedded systems environments often have stringent quality of service (QoS) and timing requirements that need to be met to ensure proper operation and dependability, even in the presence of failures and Denial of Service (DoS) attacks. Achieving this goal, however, brings about a host of critical challenges which are unique or fundamentally different from those encountered in traditional wireless sensors and ad-hoc networks. While significant progress is being made in specific technologies associated with micro-sensing and actuation, formidable barriers remain to large-scale deployment of fault-tolerant and secure embedded wireless systems for time-critical applications. This collaborative research project is pursuing integrated research at three levels: (i) reward-based, trustworthy QoS models, (ii) secure, fault-tolerant routing and data forwarding, and (iii) fault-tolerant data access and management. The emphasis of the proposed methodologies will be on the inter-relationships between different components and layers of the system and the consequent research and design issues. This project is developing comprehensive analytical framework to establish bounds on performance guarantees when failure occurs or when the system is under denial of service attacks. In pursuit of dependable,robust and secure embedded systems, this research also focuses on secure and fault-tolerant routing and data management.The project is developing scalable and energy-efficient routing protocols that can tolerate both device failures and transient network overload. The project also is developing dynamic and adaptive risk-based schemes for data aggregation and management. The effort spans several research areas: distributed and embedded real-time systems, sensor networks, security, and information processing. The project aims for impact through a wide range of time-critical applications such as: ubiquitous and pervasive health care, infrastructure protection and homeland security, and real-time environment monitoring. The project seeks to stimulate cross-area research and include a diverse group of students from Computer Science, Information Science, and Engineering. Results and software tools are freely disseminated through the project website.

Mosse-Wu 嵌入式系统环境中的时间关键型应用程序通常具有严格的服务质量 (QoS) 和时序要求，即使在出现故障和拒绝服务 (DoS) 攻击的情况下，也需要满足这些要求才能确保正常运行和可靠性。然而，实现这一目标会带来许多关键挑战，这些挑战与传统无线传感器和自组织网络中遇到的挑战是独特的或根本不同。 虽然与微传感和驱动相关的特定技术正在取得重大进展，但大规模部署用于时间关键型应用的容错和安全嵌入式无线系统仍然存在巨大障碍。该合作研究项目正在三个层面进行综合研究：(i) 基于奖励的、值得信赖的 QoS 模型，(ii) 安全、容错的路由和数据转发，以及 (iii) 容错的数据访问和管理。所提出的方法的重点将放在系统的不同组件和层之间的相互关系以及随之而来的研究和设计问题。 该项目正在开发全面的分析框架，以在发生故障或系统受到拒绝服务攻击时建立性能保证的界限。为了追求可靠、稳健和安全的嵌入式系统，本研究还重点关注安全和容错的路由和数据管理。该项目正在开发可扩展和节能的路由协议，可以容忍设备故障和瞬时网络过载。该项目还正在开发动态和自适应的基于风险的数据聚合和管理方案。这项工作涉及多个研究领域：分布式和嵌入式实时系统、传感器网络、安全和信息处理。该项目旨在通过广泛的时间关键型应用产生影响，例如：无处不在的医疗保健、基础设施保护和国土安全以及实时环境监测。该项目旨在促进跨领域研究，包括来自计算机科学、信息科学和工程学的不同学生群体。结果和软件工具通过项目网站免费传播。
