  Abstract

As computer processing power and wireless communication technology have improved, various small wireless devices have appeared, and various services based on Internet of Things technology have been released. Therefore, the demand for frequency resources has increased, and the frequency band has become saturated to the point that it is difficult to perform stable communication using existing schemes. Many configuration technologies for the CR network have been proposed to improve the efficiency of using frequency resources, but since there are many factors to consider for recognizing the wireless environment, an architecture needs to be applied to configure the CR network more effectively. In this paper, we propose a CR network architecture that supports SDN technology. In addition, we propose a DDPG-based load balancing controller architecture applicable to CR networks with the proposed structure. The experimental results in this paper show that the proposed controller effectively distributes traffic in the CR network so that frequency resources can be used efficiently.
