Abstract :

Improving system performance in terms of mobility management in a Long term evolution Advanced(LTE-A) wireless networks to increase the network performance of the system. Handover decision which is the core step of every handover decision is performed by evolved Base station. Adapting Hysteresis Margin and Time to Trigger values for the handover decision is the technique used to minimize ping pong. This paper compares algorithm based on handover criteria used, handover performance metric used, flexibility and complexity of technology used. We find that adapting multi criteria parameters help minimizes handover ping pong probability and also reduces latency of the overall system. This adaptive multi criteria technique seems to be the best solution to mitigate the effect of handover ping pong for seamless connectivity and high quality of service.
