利用移动智能:车辆雾网络中的延迟优化计算卸载

Exploiting Moving Intelligence: Delay-Optimized Computation Offloading in Vehicular Fog Networks

Sheng Zhou, Yuxuan Sun, Zhiyuan Jiang, Zhisheng Niu

摘要:

未来的汽车将拥有丰富的计算资源,以支持自动驾驶,并通过无线技术连接。因此,出现了车载雾网络(VeFN),通过计算任务卸载实现计算资源共享,提供广泛的雾应用。然而,车辆的高机动性使得很难保证整个任务卸载过程中的通信和计算延迟。在本文中,我们首先回顾了VeFN中任务卸载的最新技术,并认为移动性不仅是VeFN中及时计算的障碍,而且还可以提高延迟性能。然后,我们将机器学习和编码计算确定为解决和利用VeFN移动性的关键技术。通过案例研究,说明了如何调整学习算法以适应VeFN中的动态环境,以及如何利用机会计算卸载和任务复制的移动性。

英文摘要:

Future vehicles will have rich computing resources to support autonomous driving and be connected by wireless technologies. Vehicular fog networks (VeFN) have thus emerged to enable computing resource sharing via computation task offloading, providing wide range of fog applications. However, the high mobility of vehicles makes it hard to guarantee the delay that accounts for both communication and computation throughout the whole task offloading procedure. In this article, we first review the state-of-the-art of task offloading in VeFN, and argue that mobility is not only an obstacle for timely computing in VeFN, but can also benefit the delay performance. We then identify machine learning and coded computing as key enabling technologies to address and exploit mobility in VeFN. Case studies are provided to illustrate how to adapt learning algorithms to fit for the dynamic environment in VeFN, and how to exploit the mobility with opportunistic computation offloading and task replication.
