EAGER: Exploratory Research into Ultra Energy Efficiency in Wireless Mesh and Sensor Networks for Hazardous Environments

这个高风险、高回报的项目涉及到设计和部署无线网络的迫切需要，这些网络在危险的、放射性的环境中经得起时间的考验，例如核电站灾难。危险的放射性环境特别隐蔽，因为部署在环境中的传感和通信设备暴露于放射性辐射--因此，它们的提取以进行充电/修复是具有挑战性的，并且如果使用没有针对辐射进行加固的硬件，则它们的有效运行可能会受到严重影响，并且因为在该物理空间中需要共存不协作的无线通信技术，例如无线网状网和传感器网络。这个急切的项目探索了一条途径和解决方案，以实现在危险环境中部署的共存无线网状网和传感器网络的运行时间显著增加。智能的优点在于一种激进的新方法(锚定在新的和坚实的基于马尔可夫链的理论基础上，以实现可实现的吞吐量、延迟和能量效率)，用于使用占空比和网络编码的超能量高效无线通信协议的跨层设计。拟议研究的更广泛的社会影响超出了科学研究的传统影响，字面上影响着生死存亡。拟议的研究结果将与Response-R整合在一起，Response-R是美国国家科学基金会资助的应急研究仪器，可部署在美国各地的危险环境中，在那里它可能会拯救生命。该项目还将为研究生和本科生以及代表性不足的群体提供研究机会。

This high-risk high-reward project is concerned with the urgent need to design and deploy wireless networks that withstand time in hazardous, radioactive environments, such as a nuclear plant disaster. A hazardous, radioactive environment is particularly insidious because sensing and communication devices deployed in the environment are exposed to radioactive emissions - hence, their extraction for recharging/repair is challenging, and their efficient operation may be seriously impacted if hardware not hardened for radiation is used, and because in this physical space non-cooperating wireless communication technologies, e.g., wireless mesh and sensor networks, need to coexist. This EAGER project explores a pathway and solutions towards achieving a significant increase in the operation time of coexisting wireless mesh and sensor networks deployed in a hazardous environment. The intellectual merit lies in a radical new approach (anchored in a new and solid Markov chain-based theoretical foundation, for achievable throughput, delay and energy efficiency) for a crosslayer design of ultra-energy efficient wireless communication protocols that employ duty cycling and network coding. The broader societal impact of the proposed research goes beyond the traditional impact of scientific research, literally affecting life and death. Results of the proposed research will be integrated with RESPOND-R, an NSF-funded instrument for emergency response research, deployable in hazardous environments throughout the US, where it could possibly save lives. This project will also offer research opportunities to graduate and undergraduate students and to underrepresented groups.
