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要，这些网络能够在危险的放射性环境中经受住时间的考验，例如核电站灾难。危险的放射性环境是特别阴险的，因为部署在环境中的感测和通信设备暴露于放射性发射，因此，它们的提取用于再充电/修复是具有挑战性的，并且如果使用未针对辐射硬化的硬件，则它们的有效操作可能受到严重影响，并且因为在该物理空间中，非合作无线通信技术，例如，无线网格和传感器网络需要共存。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着增加。智力价值在于一个激进的新方法（锚定在一个新的和坚实的马尔可夫链为基础的理论基础，可实现的吞吐量，延迟和能源效率）的超节能无线通信协议，采用占空比和网络编码的跨层设计。 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，实际上影响到生死。拟议研究的结果将与RESPOND-R集成，RESPOND-R是一种由NSF资助的应急响应研究工具，可在美国各地的危险环境中部署，在那里它可能挽救生命。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.
