Diseño y evaluación de un modelo analítico para la convergencia en redes inalámbricas bajo el estándar 802.21 usando vertical handover

Abstract

Generate a convergence of wireless technologies with heterogeneous architectures is the purpose to which the current telecommunications are addressed to, because as it is evidenced in this article, you can move from an LTE network to a network such as WiMax or wireless, through the procedures of the Vertical handover, which are intended to provide users with continuous availability of connection, in space and time of the services provided by different operators. The IEEE has begun to frame such transfers under the 802.21 standard in which they disclosed several points about the connection between systems of different architectures; on this basis, we designed an algorithm that allows us to choose, in an efficient way, when and where to make the transfer of a call between heterogeneous systems. For this algorithm we used the fuzzy logic and the multicriteria decision (AHP) methods, that were simulated in R Studio, and with which it was possible to quantize the values of various criteria and define what the most appropriate network is. The fuzzy logic and the multiple criteria decision methods are applied in the area of Wireless due to, in order to make a coherent decision, we should take into account more evaluation criteria than those used in the horizontal handover; for this reason we decided to include these methods in our algorithm
