Abstract-We present in this paper a novel solution to the problem of vertical handoff for wireless networks when a mobile node carries multiple communication sessions with different QoS requirements. We solve this issue by treating it as a group decision making problem. We extend the classical AHP (Analytic Hierarchy Process) method to provide the mobile node with two types of solutions: a deterministic solution and a probabilistic one. The method we propose provides the mobile node with a wider range of parameters so as to make a more accurate decision whenhanding off to a different network.
