NeTS-ProWiN: Efficient Wireless Spectrum Utilization with Adaptive Sensing and Spectral Agility

无线应用/设备的快速增长将不可避免地耗尽无线频谱资源，因此需要更灵活和自适应的频谱管理策略和网络架构，以充分利用新兴的可编程无线电设备。本项目通过开发一种分布式自适应网络架构来解决这一挑战，该架构能够动态和有效地利用无线频谱。 它侧重于关键功能，包括频谱可用性监控，频谱访问控制和频谱使用协调。 具体而言，项目的主要任务是：（a）开发用于频谱资源的实时监视和表征的自适应、轻量级算法，（B）开发用于动态频谱利用的自适应网络架构以及分布式、跨层协调算法，（c）建立频谱捷变无线网络的分析框架并开发频谱捷变无线网络的性能基准，以及（d）通过建模、仿真和在用现成无线电设备构建的测试平台上的实验来评估上述架构和算法的性能。该项目预期（1）提高整体无线频谱效率，（2）使未授权频带无线设备或系统能够以自主和分布式方式充分利用频谱资源，（3）为监管方提供指导，以建立高效、动态的频谱管理政策;（4）鼓励新的应用充分利用智能、可编程无线电，以获得更好的服务质量;（5）为教育学生提供一个良好的工具，让他们有实践经验。 还将通过高质量的出版物和通过因特网和其他渠道分发原型实施，向工业界和学术界传播项目成果。

Rapid proliferation of wireless applications/devices will inevitably exhaust the wireless spectral resource, thus calling for more flexible and adaptive spectrum-management policies and network architectures that make best of emerging programmable radio devices.This project is addressing this challenge by developing a distributed, adaptive network architecture that enables dynamic and efficient utilization of the wireless spectrum. It focuses on key functionality including spectrum-availability monitoring, spectrum-access control, and spectrum-use coordination. Specifically, the main project tasks are: (a) development of an adaptive, lightweight algorithm for real-time monitoring and characterization of spectral resources, (b) development of an adaptive network architecture as well as distributed, cross-layer coordination algorithms for dynamic spectrum utilization, (c) establishment of an analytical framework for, and development of the performance benchmarks of, spectral-agile wireless networks, and (d) evaluation of the performance of the above architecture and algorithms via modeling, simulation, and experimentation on a testbed built with off-the-shelf radio devices.This project is expected to (1) improve the overall wireless spectral efficiency, (2) enable unlicensed band wireless devices or systems to make full use of spectral resources in an autonomous and distributed manner, (3) provide regulatory parties guidelines to establish efficient, dynamic spectrum-management policies, (4) stimulate new applications to take full advantage of intelligent, programmable radios for better quality-of-service, and (5) provide an excellent vehicle for educating students with hands-on experience. The project results will also be disseminated to industry and academia through high-quality publications and distribution of the prototype implementations via Internet and other venues.
