An Adaptive Handover Initiation Thresholdfor Seamless Mobility basedWireless Networksusing Particle Swarm Optimization (PSO) Algorithm

Abstract

In the near future mobility management, handover initiation procedure is important as it will become a necessity trend. The major problem related to mobility performance is the time required for the network to make the decision of handover. A poorly designed handover process tends to make more cases of data loss or radio link failure and thus there must be an optimum handover threshold value to ensure a seamless handover process from serving to the target base station.Throughout this work, a system for analytical handover with mathematical equations was developed and derived by using MATLAB software. This research has proposed An adaptive Reference Signal Received Power Threshold (RSRPth)to initiate the handover process by using the user's speed and the handover signaling delay value.probability of handover failure (p f ) was analyze based on the derivation of the adaptive value of RSRP th . From the obtained result, it has been found that with the developed analytical handover framework, the proposed adaptive RSRP th value for handover initiation has improved the number of handover failures.
