    The current power grid is no longer a feasible solution due to ever-increasing user demand of electricity, old infrastructure, and reliability issues and thus require transformation to a better grid a.k.a., smart grid (SG). The key features that distinguish SG from the conventional electrical power grid are its capability to perform two-way communication, demand side management, and real time pricing. Despite all these advantages that SG will bring, there are certain issues which are specific to SG communication system. For instance, network management of current SG systems is complex, time consuming, and done manually. Moreover, SG communication (SGC) system is built on different vendor specific devices and protocols. Therefore, the current SG systems are not protocol independent, thus leading to interoperability issue. Software defined network (SDN) has been proposed to monitor and manage the communication networks globally. This article serves as a comprehensive survey on SDN-based SGC. In this article, we first discuss taxonomy of advantages of SDNbased SGC.We then discuss SDN-based SGC architectures, along with case studies. Our article provides an in-depth discussion on routing schemes for SDN-based SGC. We also provide detailed survey of security and privacy schemes applied to SDN-based SGC. We furthermore present challenges, open issues, and future research directions related to SDN-based SGC.Comment: Accepte

    oai:ojs2.ojs.technoaretepublication.org:article/9Abstract - Under this research paper many different kinds of viewpoints concept of Virtualizations, the use ofvisualization for security reasons, and the Importance of IoT in the virtualization process. Moreover, this paper willsignify that Different virtual environments are offered through a virtualized IT firm, which has to be accepted andoperated if technology evolves quickly. This research paper will highlight many different types of strong andsustainable viewpoints about the visualization process and its impacts. It can be a supportive way for the nextresearcher to understand the scope of this research paper in a proper manner. In order to conduct a properunderstanding of the effect of virtualization in running a virtual instance of a computer system from actualhardware will be the main aim of this paper. On the other hand, virtualization may also be described as a techniquethat can theoretically divide a server's physical resources and use it as several, separated computers known asvirtual machines
