ADDRESSING CONSTRAINTS OF MOBILITY MANAGEMENT IN 4G NETWORK THROUGH HYBRID OPTIMIZATION TECHNIQUE

Subject Area: COMMUNICATION

This paper presents addressing constraints of mobility management in 4G network through hybrid optimization technique. Literatures were reviewed and research gap showed that despite the success of existing mobility management techniques, issues such as handover failure, signal degradation, and resource unavailability still persist in 4G networks. In this study, a hybrid optimization technique that combines Mobile-Assisted Handover (MAHO) and Network-Controlled Handover (NCHO) is proposed to address these issues. The developed technique was tested on a macro cell with load factor of 0.9, and the results show a significant improvement with 90.18% call handover success during 163 attempts.
