Abstract Future wireless networks will consist of multiple heterogeneous access technologies such as UMTS, WLAN, and WiMax. These technologies differ greatly regarding medium access scheme, network capacity, QoS support, choice of data rates, and other various parameters such as power consumption and AAA aspects. In the literature, different network access selection and handover strategies have been discussed in order to maximize the utilization for such a heterogeneous network. Thereby, it is still an open issue how to select ”inefficient” mobiles as vertical handover candidates. This work presents a novel scheme for the selection of handover candidates inWLAN hotspots. After discussing the design rationale of the decision metric, simulation studies show the impact of single and multiple handovers on remaining users in the cell.
