PERFORMANCE ANALYSIS OF OPTIMIZATION OF HOM AND CDR SOLUTION USING PSO

---

Abstract

Long-Term Evolution (LTE) is standard for wireless broadband communication that is utilized in mobile devices and data terminals. Handover procedures are considered the major function of LTE nodes. Handover margin (HOM) is considered as constant variable which is presenting threshold of difference in captured strength of signal among serving as well as target cells. Handover is implemented after time to trigger (TTT) condition is satisfied. Dropped call rate (DCR) is known as fraction of telephonic calls that are cut off because of technical issue. Reference Signal Received Power (RSRP) has been considered as power of the LTE Reference Signals spread over the full bandwidth and narrowband. The research is focusing on getting optimized HOM and DCR solution. In order to achieve the objective, the Particle swarm optimization (PSO) technique has been used considering that it will provide optimized result. Moreover, it would be capable to provide more accurate optimal solution. In other words, the use of PSO is providing more accuracy with enhanced performance. Proposed work is checking the time to get the optimum solution using PSO in case of HOM as well in case of DCR. It is concluded that PSO is taking less time. Research has provided more accurate optimal solution using PSO. Comparison of time consumption in case of optimized and non-optimized CDR and HOM has been performed. Utilization of such optimization mechanism is providing more accuracy with enhanced performance. Simulation has been performed in MATLAB environment.
