Mejoramiento del modelo basado en MLB (Mobility Load Balancing) Sobre Redes LTE

Abstract

The objective of Mobility Load Balancing over LTE networks is to manage the Radio resources be-tween adjacent cells in an efficient way to avoid the degradation of user service in scenarios where the cells are congested. This paper shows a proposal where a non-adjacent cell of a congested cell can reduce its load; in this research, will reference the procedure as Balancing by second-order. The results show that Balancing by second-order increases the overall throughput in the network by 4% and reduces the loss rate by 12% roughly compared with a traditional Mobility Load Balancing feature. The simulation includes several scenarios where the arrival rate, service rate, and length of the buffer are varied for voice traffic and low priority traffic. The model proposed in this research has a better performance than traditional load balancing algorithms in terms of loss packet rate and throughput.
