Abstract

Smart grid networks present advantages like improving reliability, security, scalability, etc. However, designing an efficient communication infrastructure for smart grid networks is a great challenge. This is because of its dependency on proprietary protocols and specific vendors. Software-defined-enabled smart grid (SDN-SG) tackles this problem by incorporating diverse protocols and standards including open source platforms. One of the most important questions in Software-defined Networking (SDN) is the controller placement problem being NP-Hard in nature. Therefore, the predominant goal of this paper is to diminish the time complexity by modeling the controller placement problem based on the holonic multi-agent system. The hierarchical structure of a holonic organization improves the computational complexity through the divide and conquer mechanism. Such an idea also decreases the distributed controllers' synchronization overhead which is an issue in the realm of SDN. On the other hand, the proper functioning of the smart grid has a strict dependency on time-critical services. Accordingly, the controller placement is supposed to be a Quality of Service-aware (QoS-aware) one. Also, intermittent topology changes in the smart grid and the occasional joining and leaving of members result in an unsteady traffic pattern and dynamicity of controller load. This research is a pioneer in providing a QoS-aware and dynamic controller placement mechanism for SDN-SG. Experimental results certify the preponderance of the approach over similar ones concerning computational complexity, packet loss, controllers’ synchronization overhead, and also load-balancing overhead.

HMLB：用于 SDN 智能电网中预防性控制器负载平衡的整体多代理方法

智能电网网络具有提高可靠性、安全性和可扩展性等优势。然而，为智能电网网络设计高效的通信基础设施是一项巨大的挑战。这是因为它依赖于专有协议和特定的供应商。软件定义的智能电网（SDN-SG）通过整合各种协议和标准（包括开源平台）来解决这一问题。软件定义网络（SDN）中最重要的问题之一是控制器的安置问题，其本质是 NP-Hard。因此，本文的主要目标是通过对基于整体多代理系统的控制器放置问题建模来降低时间复杂性。整体组织的分层结构通过分而治之的机制提高了计算复杂度。这种想法还能减少分布式控制器的同步开销，而同步开销是 SDN 领域的一个问题。另一方面，智能电网的正常运行严格依赖于时间关键型服务。因此，控制器的布置应该是服务质量感知（QoS-aware）的。此外，智能电网中拓扑结构的间歇性变化以及成员的间歇性加入和退出导致了流量模式的不稳定性和控制器负载的动态性。这项研究开创性地为 SDN-SG 提供了 QoS 感知和动态控制器放置机制。实验结果证明，该方法在计算复杂性、数据包丢失、控制器同步开销以及负载平衡开销方面优于同类方法。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
