A New Fuzzy Simulation Model for Vertical Handoff in Heterogeneous Networks (original) (raw)

2014

Abstract

In wireless technologies, there are various types of networks having different parameters and their specifications and thus having different QoS (Quality of Service). When the MS moves from one network to another network, process is known as vertical handoff. In this paper we designed the simulation model having eight parameters for vertical handoff between WWAN and cellular network with the help of Fuzzy Logic Tool Box, which is also named as FQDA (Fuzzy Logic Quantitative Decision Algorithm) and Simulink of MATLAB platform. The results show the improved performance and reduced complexity. In this work only 81 rules have been used as compared to 6561 rules needed for 8 attributes. This modified fuzzy method also result in lesser number of handoffs as compared to traditional method. KeywordsFQDA, QoS, VHO, WWAN.
