In a Fourth Generation (4G) wireless environment, the need for a user to be Always Best Connected (ABC) anywhere at any time leads to execute a vertical handoff decision for guaranteeing service continuity and Quality of Service (QoS). In this paper, vertical handover decision schemes is compared and Multi Attribute Decision Making (MADM) is used to choose the best network from the available Visitor neTworks (VTs) for the continuous connection by the mobile terminal. A comparative analysis of these methods including SAW, MEW and TOPSIS illustrated with a numerical simulation, showed the impact of the various importance weights assignment in their performance for different traffic classes and applications such as: voice and data connections, in a 4G wireless system.
