摘要

在云边缘协作系统中，确保一致的无线连接满足具有不同需求的用户的服务质量（QoS）是一项挑战。因此，应该仔细设计针对所有移动设备（MDs）的任务卸载方法，以根据不同的需求增强性能。本文提出了一种新的多目标遗传算法（MOGA）来解决任务卸载问题，同时考虑了最小的能量消耗和延迟。实验结果表明，所提出的多目标遗传算法实现了快速收敛，优化了时延和能耗。

Joint optimization of energy consumption and latency for task offloading in cloud–edge collaboration system

In a cloud–edge collaboration system, ensuring consistent wireless connectivity that meets the quality of service (QoS) for users with varying requirements is challenging. Therefore, the approach to task offloading for all mobile devices (MDs) should be carefully designed to enhance performance based on different requirements. This paper introduces a novel multi-objective genetic algorithm (MOGA) to address the task offloading problem, considering minimal energy consumption and latency simultaneously. Experimental results demonstrate that the proposed multi-objective genetic algorithm achieves rapid convergence and optimizes delay and energy consumption.
