EARS: SAVANT - High Performance Dynamic Spectrum Access via Inter Network Collaboration

该项目旨在通过无线电资源管理中的网络间合作来实现显着的频谱效率增益。 所提出的SAVANT（通过网络间协作的频谱接入）架构基于用于在相邻网络之间传播频谱使用信息、策略和算法的新协议接口，以实现频谱共存算法，从而减少干扰并提高频谱打包效率。一个新的域间频谱协调协议（ISCP）正在开发中，使独立的网络能够协商无线电资源管理策略，并有选择地合并无线电资源控制器进行联合优化。研究范围将包括ISCP协议设计/验证，评估涉及网络协作的替代算法，原型实现和性能评估。 该项目的方法包括分析，模拟和实验原型的混合。 无线电定位，传播和干扰的广义分析模型的开发，并纳入网络间的合作，使用ISCP协议框架的仿真研究。 这些仿真模型被期望提供对协作无线电资源优化算法的类型的洞察，该算法将被沿着使用，同时对ISCP开销、复杂度和性能进行定量评估。 该项目还包括一个实验性原型跟踪，其中新兴的软件定义网络（SDN）技术用于开发具有多个协作网络的概念验证系统。所提出的ISCP网络间协议具有在无线频谱利用方面大幅提高的潜力，并因此可能影响未来的行业标准。 该项目还将为软件定义网络和无线系统的研究生培训制作教材。

This project is aimed at achieving significant spectrum efficiency gains through inter network collaboration in radio resource management. The proposed SAVANT (spectrum access via inter network collaboration) architecture is based on a new protocol interface for dissemination of spectrum usage information, policies and algorithms between neighboring networks to enable spectrum coexistence algorithms that reduce interference and improve spectrum packing efficiency. A new inter-domain spectrum coordination protocol (ISCP) is being developed to enable independent networks to negotiate radio resource management policies and optionally merge radio resource controllers for joint optimization.The scope of research to be conducted includes ISCP protocol design/validation, evaluation of alternative algorithms involving network collaboration, prototype implementation and performance evaluation. The methodology for the project involves a mix of analysis, simulation and experimental prototyping. Generalized analytical models for radio localization, propagation and interference are developed and incorporated into simulation studies of inter-network cooperation using the ISCP protocol framework. These simulation models are expected to provide insight into the type of collaborative radio resource optimization algorithm to be used along with quantitative evaluation of ISCP overhead, complexity and performance. The project also includes an experimental prototyping track in which emerging software-defined network (SDN) technology is used to develop a proof-of-concept system with multiple collaborating networks. The proposed ISCP inter-network protocol has the potential for large gains in wireless spectrum utilization, and could thus influence future industry standards. The project will also produce educational materials for training of graduate students in software-defined networking and wireless systems.
