Towards Optimal Placement of Controllers in SDN-enabled Smart Grid

Modern paradigm of Software Defined Networking (SDN) inspired researchers to solve many of the network and security challenges in crucial fields such as the Smart Grids. However, integrating SDN within Smart Grid context raised many challenges in terms of network and security management such as the optimal design of SDN controller's placement. Recent researches proposed the Controller Placement Problem (CPP) to determine the optimal number and locations of SDN controllers in extremely wide area networks. In this paper, we present a solution to the CPP problem within Smart Grid context. Our simulation results demonstrate the optimal SDN controller(s) placement considering the preferred metrics and the trade-off computation between these metrics.
