Abstract: 

In cellular networks, the contradiction between traffic demands and network resources is very prominent, also mobile users can move inside the heterogeneous networks from cell to another cell. Aiming at solving these issues, efficient handover (HO) mechanisms are more and more concerned to enhance mobility management. In this paper a new handover optimization algorithm for long term evaluation (LTE) network based on fuzzy logic is presented, named Fuzzy Logic for LTE Handover (FLLH). It consists of finding the optimum handover margin (HOM) required for handover process and also finding appropriate time to trigger (TTT) to perform a success handover using fuzzy logic. FLLH handover optimization technique is evaluated and compared with the four well-known handover algorithms. The proposed handover optimization technique achieves minimum average number of handover per user and also have maximum throughput than the self-optimization technique.
