摘要

计算卸载的决策过程是移动边缘计算的一个关键方面,各种卸载决策策略与移动边缘计算系统的计算延迟和能耗密切相关。本文针对边缘计算中的 "边缘端 "架构场景,提出了一种基于增强型正余弦优化算法(SCAGA)的卸载方案。本文的研究内容包括以下几个方面:(1)建立边缘计算场景的计算资源分配模型和计算成本模型;(2)基于常春藤飞行策略正余弦优化算法的原理,结合遗传算法中常见的轮盘选择和基因突变的概念,引入增强型正余弦优化算法;(3)执行仿真实验来评估基于 SCAGA 的卸载方案,证明该方案能够有效降低系统延迟并优化卸载效用。与其他卸载方案相比,对比实验还凸显了系统延迟、移动用户能耗和卸载效用方面的改进。

Research on MEC computing offload strategy for joint optimization of delay and energy consumption.

The decision-making process for computational offloading is a critical aspect of mobile edge computing, and various offloading decision strategies are strongly linked to the calculated latency and energy consumption of the mobile edge computing system. This paper proposes an offloading scheme based on an enhanced sine-cosine optimization algorithm (SCAGA) designed for the "edge-end" architecture scenario within edge computing. The research presented in this paper covers the following aspects: (1) Establishment of computational resource allocation models and computational cost models for edge computing scenarios; (2) Introduction of an enhanced sine and cosine optimization algorithm built upon the principles of Levy flight strategy sine and cosine optimization algorithms, incorporating concepts from roulette wheel selection and gene mutation commonly found in genetic algorithms; (3) Execution of simulation experiments to evaluate the SCAGA-based offloading scheme, demonstrating its ability to effectively reduce system latency and optimize offloading utility. Comparative experiments also highlight improvements in system latency, mobile user energy consumption, and offloading utility when compared to alternative offloading schemes.
