CAREER: On Highly Efficient and Reliable Wireless Networks

该CAREER项目致力于通过先进的多层方法进行高效可靠的无线网络的基础研究。 我们关注两个问题：（一）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？(ii)当用户被授权访问网络后，如何保证信息的高效、可靠传输，特别是在恶劣的环境下？这项研究的智力价值在于开发高效可靠的无线网络的实用技术，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框架确定自己作为一个横切的研究重点，在解决现有网络的局限性和重新定义的参考框架的基础上，以网络为中心的范式通信。在信息传输方面，我们在开发高效、内在可靠的空中连接接口方面开辟了新天地。通过利用加密技术和信号检测在多个接入信道上的固有模糊性，我们设计的固有安全和高效的无线系统保证了无线网络上强大的信息机密性和完整性。首先，它为电子商务、国家安全、环境保护、健康监测以及许多可以从快速可靠的信息交换中受益的未来应用开发理想的人类技术平台奠定了坚实的基础。第二，通过将本项目产生的技术进步纳入本科/研究生课程，预计本项目将对培训无线通信和网络领域的高技能和多样化劳动力产生重大影响。第三，在这个项目中，NSF支持的工作为标准委员会提供了重要的投入，产生了广泛的工程和社会影响。

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.
