Abstract-This article presents two proposals in order to solve the problem of choosing the best access network available in the environment where the user is located. One based on a combination of fuzzy logic technique with two decision-making methods, AHP (Analytic Hierarchy Process) and GRA (Grey Relation Analysis), and the other based only on fuzzy logic technique. In order to demonstrate the effectiveness of these proposals, they were compared with a third one, of the authors in [7], which uses a combination of AHP method with a cost function. The obtained results show that the two proposals presented in this paper are more efficient in sorting and selecting the best access network when compared to the third.

Next generation wireless network (NGWN) is expected to integrate different access technologies, including cellular network, WLAN and mobile Ad Hoc network, etc., and to support users' seamless communication among different access networks. However, the heterogeneity and the diversity of access networks propose challenges on user handoff performance enhancement and system performance guarantee. In this paper, we address the problem of user QoS enhancement and system performance improvement in heterogeneous integrated system of WLAN and UMTS. Neural network (NN) based access network modeling method is proposed and an adaptive parameter adjustment algorithm based on NN model is presented. Applying the algorithm in handoff source and destination networks, user parameters can be determined optimally. The simulation results show that the proposed scheme enables the handoff user to adapt the destination network environment quickly and the variation of the throughput can be avoided efficiently. Furthermore, the network performance of the handoff source network can also be guaranteed.

Different wireless networks satisfy different users. The proposition of a single unified handoff approach is to offer the end user the quality of service (QoS) required. In this paper, vertical handoff between wireless fidelity (Wifi) and Universal Mobile Telecommunication System (UMTS) networks is investigated using MATLAB program 7.4 in order to maintain constant throughput during handoff. Three different propagation models are used. The variation of throughput with distance, received signal strength with distance and the effect of different speeds in macro and microcells are dealt with.
