Abstract


This paper proposes an architecture for next-generation networks to provide wireless heterogeneous access and seamless handover for video applications. The proposal considers different wireless technologies and adopts the IEEE 802.21standard to assist the integration of heterogeneous networks. The proposal called QoEHand (Quality of Experience Handover) Architecture presents mechanisms to predict quality of experience for the network selection phase based on neural networks, and selective discardingin congestion periods. The proposal is evaluated via simulation using the ns-2 (Network Simulator) and the performance results are presented through the QoE metrics.
