The highly motivated Software-Defined Networking (SDN), the network programmability architecture made network maintenance easy. Multiple controllers are used to provide better scalability and reliability to the network in SDN. However, to enhance the network’s performance in networks at a large scale, the placement of controllers needs to be optimized. The Wisdom of Artificial Crowds (WOAC) genetic algorithm is used to minimize propagation latency by using the fewest possible controllers. To evaluate the performance of proposed technique the Internet2 OS3E topology is considered. The proposed controller placement technique reduces latency and improves reliability by comparing the existing solutions namely Modified Density Peak Clustering (MDPC) and optimized K-means approaches. The proposed method out performs existing techniques by 10% improves in latency and maximizes the reliability.
