Ultra-Reliable and Scalable Wireless Network Testbed Powering Vehicle-to-Everything (V2X)

拟议的设备清单将用于支持PI的NSERC E.W.R. Steacie纪念奖学金研究项目“车辆到一切（V2X）的超可靠和可扩展无线网络”。******车辆可以使用低成本的无线技术交换信息。有了来自其他车辆、行人、路边基础设施和云的丰富信息，每辆联网汽车（新的甚至是旧的）都能比任何单独的驾驶员或汽车更好地看到和感知，并做出智能决策，以确保道路安全，提高交通和能源效率，减少排放，并提供信息娱乐服务。然而，可靠和可扩展的V2X无线传输在技术上具有挑战性。每一辆车，从辅助驾驶到自动驾驶，都会产生大量的信息，最多是一个人的数千倍。车辆密度可能会随着时间（非高峰期vs高峰时段）和位置（主干道vs小街）而急剧变化。在交通高峰期或交通事故中，成千上万的车辆迫切需要交换信息，却发现由于无线频谱的稀缺，服务有限或不可用，这是传统无线技术无法解决的巨大挑战。我们建议通过利用非传统硬件和软件设计的无线系统的空间容量来解决这一挑战。此外，考虑到车辆信标业务的特点，我们建议研究应用无线传感技术来提高通信可靠性和可扩展性的机会。拟议的研究计划将利用最新的无线信号处理、通信和传感技术。当地没有专门支持V2X研究项目的最新基础设施。拟议的设备采购将用于创建最先进的无线测试平台，用于开发、测试和增强超可靠和可扩展的V2X技术。

The proposed list of equipment will be used to support PI's NSERC E.W.R. Steacie Memorial Fellowship research program on "Ultra-Reliable and Scalable Wireless Networks for Vehicle-to-Everything (V2X)". ******Vehicles can exchange information using low-cost wireless technologies. With abundant information from other vehicles, pedestrians, road-side infrastructure and clouds, each connected vehicle (new or even old one) can see and sense much better than any individual driver or car, and make intelligent decisions to ensure road safety, improve transportation and energy efficiency, reduce emission, and provide infotainment services. However, reliable and scalable wireless transmissions for V2X is technically challenging. Each vehicle, from driver assisted to autonomous one, will generate a flood of information, up to thousands of times of that by a person. Vehicle density may change drastically over time (off vs. peak hours) and location (main vs. side streets). In a congested road during rush hour or due to accident, thousands of vehicles need to exchange information badly, only to find that service is limited or unavailable due to the scarcity of wireless spectrum, a grand challenge not solvable using traditional wireless technologies. We propose to address the challenge by exploiting the spatial capacity of wireless systems with non-traditional hardware and software designs. Furthermore, considering the vehicle beaconing traffic characteristics, we propose to investigate the opportunities of applying wireless sensing technology to enhance the communication reliability and scalability. The proposed research program will leverage the latest wireless signal processing, communications, and sensing technologies. There is no up-to-date infrastructure dedicated to supporting the V2X research program in the local region. The proposed equipment acquisition will be used to create a state-of-the-art wireless testbed for the development, test, and enhancement of ultra-reliable and scalable V2X technologies.
