CAREER: On Highly Efficient and Reliable Wireless Networks

这个职业项目致力于通过先进的多层方法来实现高效可靠的无线网络的基础研究。我们主要研究两个问题：(I)在用户进入网络之前，如何确保有效的基于用户的访问控制？(2)在授权用户访问网络后，如何确保有效和可靠的信息传输，特别是在恶意环境下？这项研究的智力价值在于为高效和可靠的无线网络开发实用技术，以及开发广泛适用于相关工程问题的分析和设计工具。对于访问控制，我们的相互交互的MAC-PHY框架将自己标识为解决现有网络中的限制和重新定义基于以网络为中心的范例的通信参考框架方面的横切研究重点。在信息传输方面，我们在开发高效、内在可靠的空中链路接口方面取得了新的突破。通过利用密码技术和多址接入信道信号检测中固有的模糊性，我们设计的固有安全和高效的无线系统确保了无线网络上强大的信息保密性和完整性。首先，它为电子商务、国家安全、环境保护、健康监测以及许多未来可以受益于快速可靠的信息交换的应用程序的理想人类技术平台的发展奠定了坚实的基础。第二，通过将该项目产生的技术进步纳入本科/研究生课程，预计该项目将对培训无线通信和网络领域的高技能和多样化的劳动力产生重大影响。第三，从这个项目中，NSF支持的工作为标准委员会在产生广泛的工程和社会影响方面提供了重要的投入。

This CAREER project is devoted to the fundamental research of highly efficient and reliable wireless networks through advanced multilayer methodologies. We focus on two problems: (i) Before a user enters the network, how to ensure efficient user-based access control? (ii) After a user is authorized to access the network, how to ensure efficient and reliable information transmission, especially, under malign environments? The intellectual merit of this research lies in the development of practical techniques for highly efficient and reliable wireless networks, and in the development of analytical and design tools that are broadly applicable to related engineering problems. For access control, our mutually interactive MAC-PHY framework identifies itself as a crosscutting research thrust in addressing the limitations in existing network and re-defining the reference framework for communications based on the network-centric paradigm. For information transmission, we break new ground in developing highly efficient, inherently reliable airlink interfaces. By exploiting cryptographic techniques and inherent ambiguity in signal detection over multiple access channels, our design of inherently secure and efficient wireless systems guarantees strong information confidentiality and integrity over wireless networks.The broad impacts of this project are multi-fold. First, it lays a solid foundation for the development of an ideal human technology platform for e-commerce, national security, environmental protection, health monitoring, as well as many future applications that can benefit from fast and reliable information exchange. Second, by integrating the technological advances resulting from this project into the undergraduate/graduate curricula, significant impacts are expected from this project on training a highly skilled and diverse workforce in the area of wireless communications and networking. Third, from this project, works supported by NSF provides important input to the standard committees in generating broad engineering and societal impacts.
