Marco Giordani, Takamasa Higuchi, Andrea Zanella, Onur Altintas, Michele Zorzi

摘要:

汽车正变得越来越智能化和互联化,集成了越来越多的传感器,以支持更安全、更高效的驾驶。然而,这些传感器产生的大量数据可能会使车辆通信技术的能力饱和,从而使保证所需的服务质量变得具有挑战性。从这个角度来看,必须评估每个数据源提供的信息(VoI)的价值,以优先考虑对目标应用程序最重要的传输。在本文中,我们提出并评估了一个框架,使用层次分析多准则决策过程来预测基于空间,时间和质量属性的VoI。我们的研究结果揭示了传播场景,传感器分辨率,观测类型和通信距离对价值评估性能的影响。特别是,我们表明,VoI的发展在不同的速度作为目标应用程序的特性的函数。

英文摘要:

Vehicles are becoming increasingly intelligent and connected, incorporating more and more sensors to support safer and more efficient driving. The large volume of data generated by such sensors, however, will likely saturate the capacity of vehicular communication technologies, making it challenging to guarantee the required quality of service. In this perspective, it is essential to assess the value of information (VoI) provided by each data source, to prioritize the transmissions that have the greatest importance for the target applications. In this paper, we propose and evaluate a framework that uses analytic hierarchy multicriteria decision processes to predict VoI based on space, time, and quality attributes. Our results shed light on the impact of the propagation scenario, the sensor resolution, the type of observation, and the communication distance on the value assessment performance. In particular, we show that VoI evolves at different rates as a function of the target application's characteristics.
