移动的边缘计算（MEC）允许使用其具有低延迟、位置感知和移动性支持的服务，以弥补云计算的缺点。但是过载的MEC系统或任何MEC系统故障显著地降低体验质量（QoE）并且否定MEC的优点。在本文中，我们提出了两种不同的恢复方案过载或损坏MEC。一种恢复方案是过载的MEC将其工作卸载到传输范围内的可用相邻MEC。另一种恢复方案是针对传输范围内没有可用相邻MEC的情况。第二种方案访问与过载MEC相邻的相邻MEC的用户设备作为自组织中继节点，以便桥接两个MEC之间的传输断开。数值实验验证了所提方案的性能和可行性，为未来的研究提供了有意义的结果。
Mobile edge computing (MEC) allows the use of its services with low latency, location awareness and mobility support to make up for the disadvantages of cloud computing. But an overloaded MEC system or any MEC system failure significantly degrades quality of experience (QoE) and negates the advantages of MEC. In this paper, we propose two different recovery schemes for overloaded or broken MEC. One recovery scheme is where an overloaded MEC offloads its work to available neighboring MECs within transfer range. The other recovery scheme is for situations when there is no available neighboring MEC within transfer range. The second scheme accesses user devices of a neighboring MEC adjacent to the overloaded MEC as ad-hoc relay nodes in order to bridge the transfer disconnect between two MECs. Numerical experiments demonstrated the performance and verified the possibility of the proposed schemes, providing insightful results for potential future research.
