The QoE-Oriented Heterogeneous Network Selection Based on Fuzzy AHP Methodology
The next generation of wireless communication will be characterized by heterogeneity. One of the challenges arisen is access selection among various radio access technologies. Meanwhile, the Quality of Experience (QoE) of user is becoming one of the most concerned topics. Analytic Hierarchy Process (AHP) has been popularly used in network selection, while this method is usually imprecise because consistency index in AHP does not accurately indicate users' perception. In order to deal with this problem as well as optimize the system performance, an effective fuzzy Analytic Hierarchy Process scheme for network selection is proposed in this paper, which takes the multiple criterions of Quality of Experience (QoE) into consideration.
