Vertical Handover Decision Algorithm in Heterogeneous Wireless Networks
[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.

Applying ANFIS Model in Decision-making of Vertical Handover between Macrocell and Femtocell Integrated Network
[EN] One of the most challenging tasks in
communication networks is to maintain seamless mobility and
service continuity during a vertical handover. This paper
provides the case of handover decision making between
femtocell and macrocell integrated network considering several
input parameters, namely SINR, bandwidth and energy
consumption. We have simulated and proposed a vertical
handover based on adaptive neuro-fuzzy inference system
(ANFIS) to achieve a goal of having an intelligent handover
and to predict the best destination network. The simulation
results show that the approach based on ANFIS leads to a
reduction of unnecessary handovers and a minimization of the
energy consumption as compared to the existing approaches.Benaatou, W.; Latif, A.; Pla, V. (2019).

Fuzzy Logic Based Layers 2 and 3 Handovers in IEEE 802.16e Network
International audienceIn outdoor wireless communication networks such as mobile WiMAX (802.16e), mobile stations move all the time, thus they need to be handed off to different base stations based on certain criteria. In this paper, a fuzzy logic based scheme for fast selection of best base station and of handover technique at the handover time is presented in order to minimize the delay during handover for sensitive multimedia traffic. The scheme considers several parameters such as receiver power levels, handover type, traffic type, base station load and mobile station speed for making the handover decision by the mobile station. Through simulations, we compare our proposed handover scheme based on fuzzy logic modeling with classical handover decision. And finally, we present results based on Quality of Service (QoS) criteria to confirm the validity of the proposed approach
