Intelligent handover procedure for heterogeneous LTE networks using fuzzy logic

Heterogeneous mobile networks are already a reality and their densification has been put forward as one of the suggested solutions to meet the expected demands for 5th generation (5G) mobile networks. However, in the current networks, it is still common for fixed parameters to be used for the configuration of the network although this strategy does not always prove to be efficient. It is within this context that the concept of self-organizing networks (SONs) has been established, in which several network parameters are automatically adjusted on the basis of measurements and intelligent systems in real time. This paper sets out a methodology for an intelligent handover decision in heterogeneous LTE networks based on measurements and Fuzzy logic. The results showed that the proposed algorithm is efficient and can assist in the self-organization of the network.
