[EN] With the recent progress in the area of cellular communication the issue of inter cells
handover without dropping an ongoing connection with the base station has arisen. In this paper,
the focus is on the performance of vertical handover. Various proposed interconnection
architectures for vertical handover in heterogeneous networks were studied. Two different
algorithms to make the decision on when and to which network perform a handover were
considered. In the first of them the decision is based on the received signal strength (RSS). In the
second one a fuzzy logic system that uses RSS, bandwidth, battery power and packet loss as the
input parameters is proposed. The simulation results show that the algorithm based on fuzzy
logic leads to a reduction of the number of handovers and a minimisation of the power
consumption as compared to the first algorithm used here and the existing algorithms.This work was supported by the Spanish Ministry of Economy and Competitiveness through Grants TIN2013-47272-C2-1-R and BES-2011-045551.Benaatou, W.; Latif, A.; Pla, V.
