A fuzzy logic-based Qos evaluation method for heterogeneous networks

Decision-making processes related to telecommunication networks are becoming extremely complex due to the increasing complexity of the environments, fast-growing technological evolution, rapid changes in service availability, market structure, and growing customer demands (Figueira et al., 2005). Involvement of multiple communication technologies in a single network is making the Qos evaluation of any network more complex than ever as each technology has its own characteristics and the applications running over them have their own Qos requirements. These multidimensional Qos issues in the new technological platforms lay down the ground for multi-criteria analysis methods. Multi-criteria decision-making (MCDM) or multi-attribute decision-making (MADM) algorithms have been widely used for Qos evaluation of heterogeneous networks.
