SpecEES: Collaborative Research: Energy Efficient Dynamic Spectrum Access in Uncoordinated Networks

该项目专注于节能的动态频谱接入，用户被平等对待，用户之间的协调最少，解决了在动态频谱环境中实现下一代无线通信和网络的挑战。该项目的成果将大大提高传统上服务不足的社区获得宽带无线服务的机会。所开发的频谱传感和频谱共享技术应被证明同样适用于涉及能源受限的特别网络的一系列应用，例如救灾行动中遇到的网络以及与国家安全有关的各种应用。本项目旨在培养大学生对科学、技术、工程和数学（STEM）相关领域的长期兴趣，特别是软件无线电实验。本研究项目的重点是一类动态频谱接入应用的频谱效率和能源效率，这类应用研究得很少：用户被平等对待的非协调宽带系统，即没有主要/次要区别。该项目将为此类应用开发频谱管理框架和使能技术，从使用最快变化检测的多通道频谱传感，到在没有用户协调的情况下实现频谱/能源效率和公平频谱使用的新型频谱接入方案。实验研究是拟议研究的一个组成部分，该项目利用了雪城大学开发的现有软件无线电功能。对同等特权用户无协调频谱接入的研究也填补了动态频谱接入的一个重要空白。鉴于所考虑的模型的通用性，本研究有望对最快变化检测和随机存取理论做出根本性的贡献。

With its focus on energy efficient dynamic spectrum access where the users are treated as equals and there is minimal coordination across the users, this project addresses challenges for enabling next-generation wireless communications and networking in a dynamic spectrum environment. The results from the project should greatly enhance access to broadband wireless services in traditionally under-serviced communities. The spectrum-sensing and spectrum-sharing techniques developed should prove to be equally applicable in a slew of applications involving energy-constrained ad hoc networks such as those encountered in disaster relief operations and in a variety of applications relevant to national security. The involvement of undergraduate students in this project, especially in software radio experiment, is expected to foster their long-term interest in Science, Technology, Engineering and Math (STEM)-related fields.This research project is focused on both spectral efficiency and energy efficiency for a class of dynamic spectrum access applications that have been much less well studied: an uncoordinated wide-band system where the users are treated as equals, i.e., there is no primary/secondary distinction. The project will develop the spectrum management framework as well as enabling technologies for such applications, ranging from multi-channel spectrum sensing using quickest change detection to novel spectrum access schemes for spectral/energy efficient and fair spectrum usage in the absence of user coordination. Experimental studies are an integral part of the proposed research, and the project leverages existing software radio capabilities developed at Syracuse University. This study of spectrum access with equally privileged users without coordination also fills an important gap in dynamic spectrum access. Given the generality of the models considered, this research can be expected to make fundamental contributions to the theories of quickest change detection and random access.
