"Dense deployment of cells with low radius, known as small cells, in wireless networks can notably increase an amount of initiated handovers. Consequently, the quality of service is lowered due to handover interruption and due to additional signalling overhead generated by redundant handovers. In this paper, we optimize a technique for elimination of redundant handovers denoted as an adaptive hysteresis. The adaptive hysteresis enhances conventional hysteresis by dynamic setting of current level of the hysteresis according to the relation of signal level received from serving and target cells. The improvement in performance is achieved by derivation of optimum values of parameters used in equation for determina-tion of the actual level of hysteresis. As the simulation results show, significant gain in throughput can be reached by the selection of the optimum values instead of former values de-fined for macrocells. Further, we investigate an impact of small cells density on the performance of the adaptive hysteresis. The performance improvement reached by the adaptive hysteresis is even more notable with increased density of small cells." .
