Performance analysis of Fuzzy MCDM and Game Theory based VHD models

Next generation wireless networks are evolving towards the integration of various wireless networks to provide high bandwidth and QoS support for real-time multimedia applications to mobile users in a seamless manner. Vertical Handoff Decision (VHD) problem is one of the crucial design issues that need to be resolved in order to provide seamless mobility in heterogeneous wireless environment. In this paper, we present two models to solve VHD problem based on Fuzzy MCDM and Game Theory approaches. Further we analyze the sensitivity of these models and propose an AHP based analytical model to evaluate their performance in terms of a set of decision criteria including number of parameters, user preference, scalability and elimination of unnecessary handoffs.
