Quality of experience evaluation under QoS-aware mobility mechanisms

Next generation wireless networks will encompass a wide range of heterogeneous technologies in the radio access part. In such networks, the all-IP paradigm has been identified as a promising solution that will contribute benefits by providing IP-based transport through the radio and core network parts. However, this concept requires a precise management of the userpsilas mobility, especially in order to preserve userpsilas quality of service (QoS) throughout the sessionpsilas lifetime. The aim of this paper is to evaluate the quality of experience (QoE) that users perceive when the different QoS-aware mobility management strategies adopted in the AROMA project are applied. A real-time testbed that provides end-to-edge QoS in all-IP heterogeneous wireless access networks has been employed to obtain QoE results that hardly could be obtained by means of simulations.
