摘要

自动驾驶汽车可以将自己的数据与其他车辆的数据结合起来,增强自己的感知能力,从而提高检测精度和驾驶安全性。然而,由于自动驾驶汽车上各种类型的传感器产生的大量数据,自动驾驶汽车之间的数据共享是一个具有挑战性的问题。在本文中,我们为连接和自动驾驶汽车网络提出了一种低延迟,高级别(L3)数据共享协议。基于L3协议,单个车辆产生的传感结果将在有限的传感区域内同时广播。L3协议通过利用车辆之间发生的无线传输的捕获效应来减少网络延迟。根据提出的设计原则,我们在模拟环境中实现和测试了L3协议。仿真结果表明,L3协议能够实现自动驾驶汽车之间可靠、快速的数据共享。

Low-Latency High-Level Data Sharing for Connected and Autonomous Vehicular Networks
Autonomous vehicles can combine their own data with that of other vehicles to enhance their perceptive ability, and thus improve detection accuracy and driving safety. Data sharing among autonomous vehicles, however, is a challenging problem due to the sheer volume of data generated by various types of sensors on the vehicles. In this paper, we propose a low-latency, high-level (L3) data sharing protocol for connected and autonomous vehicular networks. Based on the L3 protocol, sensing results generated by individual vehicles will be broadcasted simultaneously within a limited sensing zone. The L3 protocol reduces the networking latency by taking advantage of the capture effect of the wireless transmissions occurred among vehicles. With the proposed design principles, we implement and test the L3 protocol in a simulated environment. Simulation results demonstrate that the L3 protocol is able to achieve reliable and fast data sharing among autonomous vehicles.
