边缘计算被认为是一种很有前途的范例，可以弥补实时移动增强现实(MAR)对计算的苛刻要求和移动设备有限的计算能力之间的差距。然而，在许多实际情况下，现有的边缘辅助MAR的工作可能无法达到预期的性能，例如，无线链路不稳定和用户移动性造成的不可修复的网络中断，这是流行的MAR应用的关键特征。在本文中，我们设计了一种新的基于边缘的MAR系统--Explorer，它使移动用户即使在网络不稳定和频繁的用户移动的情况下也能获得有保证的MAR卸载性能。此外，还开发了分析模型以提供对目标检测过时来源的及时估计。此外，我们在端到端的测试床上实现了所提出的浏览器。
Edge computing is proposed to be a promising paradigm to bridge the gap between the stringent computation requirement of realtime mobile augmented reality (MAR) and the constrained computation capacity on our mobile devices. However, prior work on edge-assisted MAR may fail to achieve expected performance in multiple practical cases, e.g., irreparable network disruptions caused by wireless link instability and user-mobility which is a critical characteristic of popular MAR applications. In this paper, we design a new edge-based MAR system named Explorer that enables mobile users to acquire guaranteed MAR offloading performance even under network instability and frequent user-mobility. Additionally, analytical models are developed to provide timely estimation of the sources of object detection staleness. Furthermore, we implement the proposed Explorer in an end-to-end testbed.
