摘要:
多接入边缘计算(MEC)已经成为一种重要的范式,通过使用 MEC 技术,终端设备可以将其计算任务卸载到邻近的边缘服务器或远程云服务器上执行。 但对于庞大的任务量而言,它们的计算能力、内存和能源仍然受限。 如何进行有效的任务分流至关重要。 该文允许任务在三个位置(本地设备、边缘端、云端)处理,有效避免了传统的二元规划机制缺乏灵活性,不考虑任务依赖等问题。 并提出了一种河马优化算法(HOA)与改进型强度 Pareto 进化算法(SPEA2)相结合的多目标河马优化算法(MHOA)。 MHOA 算法充分利用 HOA 的全局搜索能力和多样性维护等特点,以及 SPEA2 中 Pareto 前沿优化和局部开发能力,并采用特定的初始化算法,在考虑任务依赖关系的同时,解决边缘云计算环境下多用户依赖任务的卸载问题,同时最小化执行时延、能耗、资源使用成本三个约束。 将 MHOA 与其他优化算法进行了比较,结果表明MHOA 在适应度方面比第二优的优化器优化了 3. 5% 。
Abstract:
Multi-access edge computing (MEC) has become an important paradigm,allowing devices to offload their computations to nearby edge servers or remote cloud servers. However,given the vast amount of tasks,their computing power,memory,and energy are still limited. Effective task offloading is crucial. We allow tasks to be processed in three locations ( local device,edge end,cloud),effectively avoiding the traditional binary planning mechanism lack of flexibility,does not consider task dependence and other problems.And we propose a Multi-objective Hippo Optimization Algorithm (MHOA) that combines the Hippo Optimization Algorithm (HOA) with the Strength Pareto Evolutionary Algorithm (SPEA2). This approach leverages HOA’s global search capability and diversity main-tenance,as well as SPEA2 ’s Pareto frontier optimization and local development capabilities, and incorporates a specific initialization algorithm. While considering task dependencies, it addresses the problem of multi - user dependent task offloading in edge cloud computing environments,aiming to minimize execution delay,energy consumption,and resource usage cost. MHOA is compared with other optimization algorithms,and the results show that MHOA outperforms the second-best comparator by 3. 5% in terms of fitness.
