An enhanced fuzzy logic optimization technique based on user mobility for LTE handover

In previous cellular networks, changing the parameters of handover manually was time consuming. So, automatic change of the parameters of handover will decrease expenditures, save time and guarantee the best quality of service. A new efficient handover optimization technique for Long Term Evolution (LTE) based on fuzzy logic is proposed in this paper. It is evaluated in terms of average number of handover, system throughput, and system delay based on user equipment (UE) speed. The most important contribution of this work that UE speed is considered in the handover process. The suggested optimization technique will select effective time-to-trigger (TTT) based on the UE speed, and it will also find the optimum handover margin (HOM) required for the handover process. This new handover optimization technique is evaluated for the four well-known handover algorithms then compared together. The proposed algorithm achieves a significantly improve in the handover performance when compared with the standard LTE and self-optimization technique.
