Adaptive Techniques for Elimination of Redundant Handovers in Femtocells
Dense deployment of femtocells in mobile wireless networks can significantly increase the amount of handover initiations. This paper analyzes new approach to elimination of redundant handovers. The innovative way dynamically updates current value of techniques commonly used for elimination of redundant handovers. The goal is to investigate the efficiency of two handover elimination techniques, i.e., windowing and handover delay timer. Both techniques are modified to enable adaptation of their parameter according to the channel quality related to the users' position in the cell. Furthermore, the impact of proposed modifications on the user's throughput is examined.
