MODELLING OF INTELLIGENT HANDOVER DECISION ALGORITHM FOR 4G MOBILE NETWORK USING GENETIC ALGORITHM

Subject Area: COMMUNICATION

This paper presents the modeling of intelligent handover decision algorithm for 4G mobile network using genetic algorithm. The aim is to ensure that the best cell is chosen in a heterogeneous network for the management user carriers. This was achieved developing a genetic algorithm which help the bigger cell (Macro) to make decision based on key indicator attributes like signal to noise ratio, signal to interference and noise ratio, reference signal receive power, among other attributes for quality of service in 4G network and then handover for better management. The models were developed using mathematical methods, structural methods and pseudocode for the handover algorithm. These were implemented with Simulink and evaluated. The result showed that the macro cell was able to choose the best cell available at the time of handover within the network and make decision.
