GravCPA: Controller Placement Algorithm Based on Traffic Gravitation in SDN
Journal of Control Science and Engineering, 2022 Software-defined network separates the control plane and the data plane, making the network more flexible. With the expansion of the network scale, one centralized controller cannot meet the latency needs of large-scale networks.

Joint Latency and Reliability-Aware Controller Placement [PDF]
2021 International Conference on Information Networking (ICOIN), 2021 In network architectures based on Software Defined Networking (SDN) the control plane (control logic) is separated from the network data plane (forwarding plane) while traditional network routers combine both. Software Defined networks facilitates a centralized networking system where a logical controller manages the global view of the network. In this

The role of inter-controller traffic in SDN controllers placement
2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2016 We consider a distributed Software Defined Networking (SDN) architecture adopting a cluster of multiple controllers to improve network performance and reliability. Differently from previous work, we focus on the control traffic exchanged among the controllers, in addition to the Openflow control traffic exchanged between controllers and switches.

A Novel Placement Strategy for FACTS Controllers [PDF]
IEEE Power Engineering Review, 2002 In this paper, a new method called the extended voltage phasors approach (EVPA) is proposed for placement of FACTS controllers in power systems. While the voltage phasors approach (VPA) identifies only the critical paths from the voltage stability viewpoint, the proposed method additionally locates the critical buses/line segments.
