Reinforcement learning for Admission Control in 5G Wireless Networks
This addresses admission control for 5G wireless networks, but it is incremental as it applies an existing reinforcement learning method to a specific domain problem.
The paper tackled the admission control problem in 5G wireless networks by comparing a threshold policy with a reinforcement learning-based policy, finding that the reinforcement learning policy outperformed in scenarios with heterogeneous time-varying arrival rates and multiple user equipment types.
The key challenge in admission control in wireless networks is to strike an optimal trade-off between the blocking probability for new requests while minimizing the dropping probability of ongoing requests. We consider two approaches for solving the admission control problem: i) the typically adopted threshold policy and ii) our proposed policy relying on reinforcement learning with neural networks. Extensive simulation experiments are conducted to analyze the performance of both policies. The results show that the reinforcement learning policy outperforms the threshold-based policies in the scenario with heterogeneous time-varying arrival rates and multiple user equipment types, proving its applicability in realistic wireless network scenarios.
