… has a negative impact on delay between switches and controllers. Our objective is to find
the optimal placement of SDN controllers that reduces the cost between controllers from one …

… Thus, CPP is aimed at finding the optimal location of the SDN controllers in a manner that
achieves various defined objectives such as latency minimization, load balancing, energy …

… This research paper addresses the optimal placement of SDN controllers. In fact, SDN
topology should be designed carefully to guarantee performance parameters. To this end, we …

… SDN controllers that communicate with the network devices through Application Programming
Interfaces (API) [1]. SDN … Thus, the migration of the networks towards SDN based networks …

… We find that our approach performs near to optimal and better than state-of-the-art … the
controller placement problem in edge networks in Section III. In Section IV, we present optimal and …

… Apart from this, we also propose a modular design of an SDN controller such that the
above algorithms can be implemented in practice. To extend this proposal to real …

… operators in the placement of SDN controllers. Since the SDN controllers are responsible to
… method was employed to find the optimal placement that minimizes the average latency and …

… based optimal placement (POCO toolset) in MATLAB to achieve optimal placement of controllers.
… This is the first mathematical model for the SDN controller placement. They use CPLEX …

… problem in different use cases, we propose corresponding algorithms to find near-optimal
solutions based on the covered set concept of submodularity. Although this problem invokes …

… of old particle and also find the optimum placements. Lines 27 to 32 give the optimum
placement (optmPlacement) of controllers and minimum latency (optmLatency) of reliable SDN. …
