Collaborative Research: Multi-Scale QoS for Body Sensor Networks

这一合作研究项目的目标是解决与无线身体传感器网络(BSN)相关的关键服务质量(Qos)问题，使其在各种医疗应用中对个人进行连续、非侵入性的监测变得实用和有效。该方法是开发新的系统建模和分析技术，用于应用程序保真度、网络延迟和吞吐量以及能量的设计时优化和运行时管理。该项目的主要特点是多尺度的服务质量方法，使设计人员能够探索每个系统级别的技术如何影响其他级别。这项工作将在实际BSN应用中部署的物理BSN系统的实验基础上得到验证和改进。从智能方面的优势来看，本研究解决了在严格的资源约束、复杂的环境和不同的应用语义和上下文下实现高水平的服务质量的问题。虽然分层的服务质量管理方法适用于资源密集型系统，但BSN需要一种集成的、多尺度的方法，能够跨系统级别找到操作点，以根据应用特定的要求和动态运行条件最大化服务质量指标。就更广泛的影响而言，本研究中解决的服务质量问题是BSN最终在其承诺的医疗保健应用程序中被接受的核心。该项目包括与医生和护士的互动，以确保BSN满足实际应用的要求，包括在家庭医疗保健和辅助生活环境中的部署。该项目还试图通过亲身实践演示和引人注目的应用程序的明确链接，让年轻学生对工程学产生兴趣。

The objective of this collaborative research project is to address the key quality of service (QoS) issues related to wireless body sensor networks (BSNs) to make them practical and efficacious for continuous, non-invasive monitoring of individuals in a variety of healthcare applications. The approach is to develop new system modeling and analysis techniques for design-time optimization and run-time management of application fidelity, network latency and throughput, and energy. The key feature of this project is the multi-scale approach to QoS, enabling designers to explore how techniques at each system level impact the other levels. This work will be validated and improved upon based on experimentation with physical BSN systems deployed in real BSN applications.With respect to intellectual merit, this research address the problem of achieving high levels of QoS under severe resource constraints, in complex environments, and with varying application semantics and contexts. While a layered approach to QoS management is appropriate for resource-heavy systems, BSNs require an integrated, multi-scale approach capable of finding operating points across system levels to maximize QoS metrics based on application-specific requirements and dynamic operating conditions.With respect to broader impact, the QoS issues addressed in this research are central to the ultimate acceptance of BSNs in the healthcare applications for which they have such promise. This project includes interactions with doctors and nurses to ensure that BSNs are addressing the requirements of real applications, including deployment in home healthcare and assisted living settings. The project also seeks to get young students excited about engineering through hands-on demonstrations and clear links to compelling applications.
