Most current self-organization networking functions apply rule-based recommended systems to control network resources which seem too compli- cated and time-consuming to design in practical conditions. This research proposes a cog- nitive cellular network empowered by an efcient self-organization networking approach which enables SON functions to separately learn and fnd the best confguration setting. An efective learning approach is proposed for the functions of the cognitive cellular network, which exhibits how the framework is mapped to SON functions. One of the main func- tions applied in this framework is mobility load balancing. In this paper, a novel Stochastic Learning Automata has been suggested as the load balancing function in which approxi- mately the same quality level is provided for each subscriber. This framework can also be efectively extended to cloud-based systems, where adaptive approaches are needed due to unpredictability of total accessible resources, considering cooperative nature of cloud environments. The results demonstrate that the function of mobility robustness optimiza- tion not only learns to optimize HO performance, but also it learns how to distribute excess load throughout the network. The experimental results demonstrate that the proposed scheme minimizes the number of unsatisfed subscribers (N us ) by moving some of the edge users served by overloaded cells towards one or more adjacent target cells. This solution can also guarantee a more balanced network using cell load sharing approach in addition to increase cell throughput outperform the current schemes.
