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

这个高风险、高回报的项目关注的是设计和部署无线网络的迫切需求，这些网络可以在危险的、放射性的环境中经受住时间的考验，比如核电站灾难。危险的放射性环境尤其危险，因为在环境中部署的传感和通信设备暴露在放射性排放中，因此，提取它们进行充电/维修是具有挑战性的，如果使用的硬件没有针对辐射进行加固，它们的有效运行可能会受到严重影响，并且因为在这种物理空间中，无线网格和传感器网络等非合作无线通信技术需要共存。这个EAGER项目探索了一种途径和解决方案，以实现在危险环境中部署的共存无线网格和传感器网络的运行时间的显著增加。智力上的优点在于一个全新的方法（锚定在一个新的和坚实的基于马尔可夫链的理论基础上，实现吞吐量、延迟和能源效率），用于采用占空比和网络编码的超节能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传统的科学研究的影响，实际上影响到生命和死亡。拟议的研究结果将与美国国家科学基金会资助的应急响应研究仪器response - r相结合，可在美国各地的危险环境中部署，可能会挽救生命。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.
