摘要

从最近的研究中可以观察到,尽管云计算在存储、计算和网络服务方面提供了最大的性能,但物联网(IoT)仍然存在高处理延迟、位置感知和最少移动支持的问题。为了解决这些问题,本文将雾计算与软件定义网络(SDN)相结合。重要的是,雾计算将计算和存储扩展到网络边缘,这可以最大限度地减少延迟以及移动性支持。此外,本文旨在结合一种新的优化策略来解决延迟最小化方面的“负载平衡”问题。提出了一种新的阈值鲸优化算法(T-WOA),用于优化选择负载分配系数(完成任务的时间分配)。最后,将该模型的性能与其他有关延迟的传统模型进行了比较。仿真结果表明,基于SDN的T-WOA算法在软件定义云/雾架构下能够有效地降低时延,提高服务质量(QoS)。

Load balancing strategy in software defined network by improved whale optimization algorithm
From the recent study, it is observed that even though cloud computing grants the greatest performance in the case of storage, computing, and networking services, the Internet of Things (IoT) still suffers from high processing latency, awareness of location, and least mobility support. To address these issues, this paper integrates fog computing and Software-Defined Networking (SDN). Importantly, fog computing does the extension of computing and storing to the network edge that could minimize the latency along with mobility support. Further, this paper aims to incorporate a new optimization strategy to address the “Load balancing” problem in terms of latency minimization. A new Thresholded-Whale Optimization Algorithm (T-WOA) is introduced for the optimal selection of load distribution coefficient (time allocation for doing a task). Finally, the performance of the proposed model is compared with other conventional models concerning latency. The simulation results prove that the SDN based T-WOA algorithm could efficiently minimize the latency and improve the Quality of Service (QoS) in Software Defined Cloud/Fog architecture.
