Despite the presence of wireless connectivity in most terrestrial scenarios, there are still many extreme environments that cannot be covered, including underground, underwater, and confined spaces (tunnels, pipelines, and indoor environments with no network infrastructures). Wireless networks in such environments can enable various applications, ranging from environmental sustainability, homeland security, to military and defense automation. However, existing wireless networking techniques, including electromagnetic wave-based solutions, acoustic wave-based solutions, and magnetic induction-based solutions, do not work in the aforementioned extreme environments, especially when the target environment has lossy media and complex structure and when the device is small and mobile. In this project, a new networking paradigm, Metamaterial-inspired Networking (MetaNet), will be developed to wirelessly internetwork portable (or even smaller) devices in extreme environments. MetaNet will generate significant impacts by providing a new networking platform to establish wireless connection in extreme environments. It can positively impact many human activities and can eventually address many key problems, such as increasing oil/gas recovery factor, protecting groundwater, mitigating the impacts of natural disasters, establishing smart cities and smart buildings, and enhancing the safety of military and law enforcement personnel. In this project, education will be integrated with the research through a distance education program focusing on everywhere wireless networking, a new graduate level course and a senior level capstone course, and a tech summer camp to reach out to K-12 students.In this MetaNet project, each wireless device is equipped with a software-defined micro-coil-antenna array (i.e., a smart metamaterial layer) and uses the Metamaterial-enhanced Magnetic Induction (M2I) technique to establish network links. M2I helps each node to achieve reasonable communication range (tens of meters with pocket-sized devices) in various hostile and complex environments. Moreover, since M2I significantly enhances the magnetic coupling among the wireless devices as well as the conductive objects in the environment, the much closer interactions among all the nodes as well as the environment create both opportunity and risk for network design. The objective of this project is to explore for the first time the fundamentals of metamaterial-inspired networking in various extreme environments through a closed-loop combination of mathematical modeling, simulations, and experimental evaluation. This proposed plan is based on four core intertwined research tasks: (i) physical layer solutions based on channel analysis of M2I communications in various environments; (ii) environment-aware and cross-layer network control techniques; (iii) network topology-discovery and localization algorithms; and (iv) prototyping and performance evaluation through a MetaNet testbed and a cross layer simulator.

尽管在大多数陆地场景中都存在无线连接性，但仍然有许多无法覆盖的极端环境，包括地下，水下和狭窄的空间（隧道，管道，管道和没有网络基础架构的室内环境）。在这种环境中的无线网络可以实现从环境可持续性，国土安全到军事和国防自动化的各种应用程序。但是，现有的无线网络技术，包括基于电磁波的解决方案，基于声波的解决方案和基于磁感应的解决方案，在上述极端环境中不起作用，尤其是当目标环境具有有损的媒体和复杂的结构以及设备小且可移动时。在这个项目中，将开发出新的网络范式，超材料启发的网络（metanet），以在极端环境中无线互联网可移植（甚至更小）设备。 Metanet将通过提供一个新的网络平台来在极端环境中建立无线连接，从而产生重大影响。它可以积极影响许多人类活动，并最终可以解决许多关键问题，例如增加石油/天然气恢复因素，保护地下水，减轻自然灾害的影响，建立智能城市和智能建筑，并提高军事和执法人员的安全。在该项目中，教育将通过一项远程教育计划与研究融合，该计划重点是无线网络，新的研究生水平课程和高级级别的顶峰课程以及与K-12学生接触的技术夏令营。在这个元网络项目中，每个无线设备都配备了软件定义的微型固定型阵列（即智能的地铁（即智能），并配备了MetAmpection（即，MetAmpeciption）（即MetAmpection）（即MetAmpation）。建立网络链接。 M2i帮助每个节点在各种敌对和复杂的环境中实现合理的通信范围（具有袖珍设备的数十米）。此外，由于M2I显着增强了无线设备之间的磁耦合以及环境中的导电对象，因此所有节点之间的近距离交互以及环境之间的相互作用更加紧密，既创造了网络设计的机会和风险。该项目的目的是首次通过数学建模，模拟和实验评估的闭环组合在各种极端环境中首次探索超材料启发的网络的基础。该提出的计划基于四个核心相互交织的研究任务：（i）基于各种环境中M2I通信的渠道分析的物理层解决方案； （ii）环境意识和跨层网络控制技术； （iii）网络拓扑结构和本地化算法； （iv）通过元网络测试床和横层模拟器进行原型和性能评估。
