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).

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.

Performance Evaluation of the Vertical Handover in the Wireless Networks
[EN] In mobile communication, Vertical handover is a process when a mobile switches from one network to another without any interruption.
This paper gives three different proposed types of interworking architectures were designed between WLAN, UMTS and WiMAX networks based on the quality of service (QoS). Performance and evaluation of handover based on various parameters like handover delay,
received power, signal to noise ratio, throughput, Traffic sent and traffic received is done and the performance of the interworking architecture is analyzed from the simulation results using OPNET Modeller 14.5.Benaatou, W.; Latif, A.; Pla, V.
