Load Balancing in a Realistic Urban Scenario for LTE Networks

In this paper the behavior and the self-optimization of an LTE network under realistic conditions are investigated. To enhance network performance in a urban environment a controller to auto-tune parameters has been proposed. An urban mobility model has also been defined in order to test the proposed method under realistic conditions. This model allows to investigate some performance features, which are not visible with a simple mobility model. In this paper, we propose to use a Fuzzy Logic Controller (FLC) for the optimization of handover parameters for adaptive load balancing. Results show that under an agglomeration of vehicles in a main road of the scenario, the proposed method achieves an improvement in the global Call Blocking Ratio (CBR).
