EAGER: CDRIVE: Cognitive Radio Enabled Spectrum Aware Intelligent Vehicular Networks

传输高带宽内容在车辆和移动的网络中是一个挑战，这些网络受到未授权频带中的频谱稀缺性、短连接时间和蜂窝数据计划成本的限制。这些观察激励使用频率捷变认知无线电作为称为CDRIVE（用于支持认知无线电的可感知的智能车辆网络）的项目的一部分。CDRIVE涉及理论分析工具的使用和相关函数的探索。一个主要的贡献在于创建一个新的ns-2为基础的仿真工具，结合频谱相关的功能，在认知无线电在车辆环境。CDRIVE致力于为车辆认知无线电网络开发一个整体框架，用于分配具有频谱数据库访问能力的路边基站位置，增强在不同地形条件下收集频谱测量的科学性，周围的城市结构和速度，并设计一种新的速率控制机制，预测网络和相关道路中断，以及由于频谱中断而造成的间歇性中断。CDRIVE将在认知无线电与频谱数据库的集成方面产生深刻的见解，特别是对于移动的网络，这是FCC现在规定的。它将提供最佳的移动感知频谱感知策略的理论和实践验证，并紧密耦合的外部环境与感知方法。它还将塑造未来车辆中与安全相关的消息传递，支持实时遥测分析，并为应急响应人员提供高带宽通信。

Transferring high bandwidth content is a challenge in vehicular and mobile networks that are limited by spectrum scarcity in the unlicensed bands, short connection times, and the cost of cellular data plans. These observations motivate the use of frequency agile cognitive radios as part of the project called CDRIVE (for Cognitive raDio enabled spectRum-aware Intelligent Vehicular nEtworks). CDRIVE involves the use of theoretical analysis tools and exploration of correlation functions. A major contribution lies in creating a new ns-2 based simulation tool that combines spectrum-related functions in a cognitive radio within a vehicular environment. CDRIVE makes advances towards developing a holistic framework for vehicular cognitive radios networks for allocating roadside base station locations that have spectrum database access capability, enhancing the science of collecting spectrum measurements under different topographical conditions, surrounding urban structures and speeds, and devising a new rate control mechanism that anticipates network and correlated road congestions, and intermittent disruptions due to spectrum outages. CDRIVE will yield insights on integrating cognitive radios with spectrum databases, especially for mobile networks, which are now mandated by the FCC. It will provide the theory and practical validation of the best mobility-aware spectrum-sensing strategies, and tightly couple the external environment with the sensing method. It will also shape future safety-related messaging in vehicles, support real-time telemetry analysis, and allow high-bandwidth communication for emergency response personnel.
