Abstract:
Ultra-Dense Networks (UDNs) were introduced to improve the network coverage and support high data rate services. However, the dense deployment of small cells generates an uneven traffic distribution. The unbalanced load causes performance degradation and may be responsible for radio link failures. To address this problem, this paper proposes proactive algorithms to balance the load across the small cells based on the previous user transfer and the reactive algorithms. The proactive algorithms distribute the users, one by one, to the access points, while the reactive ones are only triggered when the load of the chosen small-cell cluster reaches a predefined threshold. The user transfer algorithms offload the small cells by transferring the extra users to the macrocells. The user transfer can be occurred before or after balancing the load by the reactive algorithms. The results indicate that the transfer_after algorithm improves the load distribution and the balance efficiency better than the proactive algorithm with the transfer_before algorithm by 3.46% and 15.71%, respectively.
