Adaptive weight factor estimation from user preferences for vertical handoff decision algorithms

Estimating weight factors for QoS parameters plays an important role in the effectiveness of vertical handoff decision algorithms. This paper presents a novel weight estimation technique, which can adaptively control the spanning of the weights in response to user preference. Simulation results show the supremacy of the technique against the state-of-the-art in achieving wider spanning of the expected values of all QoS parameters under consideration.
