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.

嵌入式系统环境中的Mosse-Wutime关键应用通常具有严格的服务质量（QoS）和时序要求，即使在存在失败和拒绝服务（DOS）攻击的情况下，也需要满足适当的操作和可靠性。然而，实现这一目标，带来了许多关键挑战，这些挑战与传统无线传感器和临时网络中遇到的目标是独特或根本不同的。 尽管与微观感应和致动相关的特定技术正在取得重大进展，但可强大的障碍仍在大规模部署耐故障和安全的嵌入式无线系统中，以进行时间关键应用。该协作研究项目正在进行三个级别的综合研究：（i）基于奖励的，值得信赖的QoS模型，（ii）安全，容忍故障的路由和数据转发，以及（iii）容忍错误的数据访问和管理。所提出的方法的重点将是系统的不同组件和系统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拒绝服务攻击时建立绩效保证的界限。为了追求可靠，健壮和安全的嵌入式系统，这项研究还关注安全且容忍故障的路由和数据管理。该项目正在开发可扩展和节能的路由协议，这些协议可以容忍设备故障和瞬态网络过载。该项目还为数据聚合和管理开发了动态和自适应风险方案。这项工作涵盖了几个研究领域：分布式和嵌入的实时系统，传感器网络，安全性和信息处理。该项目旨在通过广泛的关键时期应用来影响：无处不在和普遍的医疗保健，基础设施保护和国土安全以及实时环境监测。该项目旨在刺激跨区域的研究，并包括来自计算机科学，信息科学和工程学的各种学生。结果和软件工具通过项目网站自由传播。
