Collaborative Research: CSR---EHS: An Open, Dependable and Evolvable Software Infrastructure for Assisted Living

婴儿潮一代的老龄化已经成为一个社会和经济挑战。随着美国65岁以上的居民人数预计将翻一番（从2000年的3500万增加到2030年的7000万），以及美国医疗保健支出的增长（一些来源预计到2010年将达到GDP的15.9%），老年人护理的成本是社会以及未来社会保障和医疗保险计划的关键问题。该项目旨在设计、实施和评估支持辅助生活的基础设施技术，强调：(i)允许不同技术、软件组件和不同协议族的无线设备以低成本、可靠和安全的方式协同工作，并具有可预测的特性的软件基础设施；（ii）为不懂技术的用户调整软件基础架构的界面，并结合社交透明度，以提供用户控制的隐私。为了实现这一目标，该项目力求发展以下方面：(1)可靠、健壮、即插即用的基础设施，用于协调传感、定位、通信和事件/数据管理；(2)服务质量注释和分析技术，用于明确COTS组件接口的假设和机器可检查；(3)基于角色的访问控制和工作流建模技术，用于严格的安全和隐私框架；(4)QoS管理器，用于处理工作量激增并调整不同服务的QoS设置；(5)允许各种无线设备和协议栈和谐共存的干扰缓解技术，共享未经许可的频段；(6)人机交互（HCI）组件，解决如何向用户呈现定向和环境信息、提醒和警报，以及用户可以在多大程度上控制信息披露的程度。

The aging of baby boomers has become a social and economical challenge. With an expected doubling of the number of US residents over age 65,(from 35 million in 2000 to 70 million in 2030) and the growth of US expenditures for health-care (projected by some sources to reach 15.9% of GDP by 2010), the cost of senior care is a critical issue for society and for the future of Social Security and Medicare programs. This project aims to design, implement, and evaluate infrastructure technologies to support assisted living, emphasizing: (i) software infrastructure that allows disparate technologies, software components, and wireless devices of different protocol families to work together in a low cost, dependable, and secure fashion with predictable properties; (ii) an interface that adapts this software infrastructure for technology-naive users and incorporates social translucency to provide user-controlled privacy.To achieve the goal, the project seeks to develop the followings: (1) dependable, robust, plug-and-play infrastructure that coordinates sensing, localization, communication, and event/data management, (2) Quality-of-service annotation and analysis technologies that make assumptions explicit and machine checkable for COTS component interfaces, (3) role-based access control and workflow modeling techniques for a rigorous security and privacy framework, (4) QoS manager that handles the surges of workload and adjusts QoS settings of difference services, (5) interference mitigation techniques that allows various wireless devices and protocol stacks co-exist harmoniously sharing the unlicensed frequency band, and (6) a Human Computer Interaction (HCI) component that addresses how directed and ambient information, reminders and alerts should be presented to users and to what extent users can control the degree of information disclosure.
