In distributed SDN controllers with mobility, communication between controllers becomes unstable due to movement, resulting in overall network performance degradation. Therefore, in this paper, we propose the Mobility-Aware Leader Controller Selection (MLCS) method that selects the leader of the controller considering mobility in distributed SDN. MLCS calculates the stability value of the controller in a dynamic environment by forming a virtual ring through leader/candidate controller selection. Simulation results prove that MLCS significantly reduces communication costs while maintaining overall network performance through self-organization between controllers.
