Collaborative Research-NETS-NOSS: AutoNomouS netWorked sEnsoR Systems (ANSWER)

大规模部署的传感器聚合有望创建复杂的传感、计算、通信和控制平台，称为网络传感器系统(NSS)，它将渗透到社会中，彻底改变我们的生活和工作方式。为了扩大规模，这些系统必须在很大程度上是自治的、分散的实体，其公司资源可以向授权用户提供。这种自治的、地理上分散的NSS越来越被认为是从医疗保健到智能家居和国土安全等众多应用的关键。例如，自主NSS可以通过定位幸存者、识别危险区域和提高用户对情况的认识来协助急救人员，通常是在不适宜居住的环境中。资源有限的传感器、无线通信媒介、大规模部署，再加上用户的移动性、与物理环境的密切互动以及关键任务作业的高度敏感性，对自主NSS的设计构成了巨大的挑战。该项目的主要相关技术贡献是：(1)基于任务的动态联网，支持应用级任务和查询，同时隐藏资源级细节；(2)智能AFN移动性，随应用需求和网络条件的变化而变化；(3)提供安全的应答操作和与现场移动用户的多级安全交互。Answer Prototype可以作为一种工具，在不同的环境和网络条件下探索泛在网络中移动用户的行为。该项目将利用VT、UMBC和ODU的计划，积极招募代表不足的群体，并让他们参与泛在网络、安全和传感器系统方面的创新多学科动手实验。研究结果将通过该项目的网站(http://www.nve.vt.edu/cias/cycarenet/ANSWER).发布

Aggregations of massively deployed sensors are expected to create sophisticated sensing, computation, communication and control platforms called Networked Sensor Systems (NSS) that will pervade society, revolutionizing the way in which we live and work. In order to scale, these systems must be largely autonomous, decentralized entities whose corporate resources can be made available to authorized users. Such autonomous, geographically-dispersed NSS are increasingly recognized as key to numerous applications ranging from healthcare to smart homes and homeland security. For example, autonomous NSS can assist first responders, often in inhospitable environments, by locating survivors, identifying danger areas and enhancing user awareness of the situation The resource-constrained sensors, the wireless communication medium, the large-scale deployment, combined with the mobility of users, the close interaction with the physical environment and the highly sensitive nature of mission-critical operations pose formidable challenges to autonomous NSS design. The key inter-related technical contributions of this project are: (1) Dynamic task-based networking supporting application-level tasks and queries while hiding resource-level details; (2) Smart AFN mobility subject to changing application requirements and network conditions; and (3) providing secure ANSWER operation and multi-level secure interactions with in-situ mobile users. ANSWER prototype can serve as a tool to explore mobile user behavior in ubiquitous networks under varying environmental and network conditions. This project will leverage programs at VT, UMBC, and ODU to actively recruit and involve under-represented groups in innovative multi-disciplinary hands-on experiments in ubiquitous networking, security and sensor systems. The research results will be disseminated via the project's Web site (http://www.nve.vt.edu/cias/cycarenet/ANSWER).
