“…application) metrics that can better reflect the end user's QoE than network QoS requirements. In [9], QoE metrics are used to design a handover system for heterogeneous multimedia wireless networks. In [10], a cross-layer scheduling and resource allocation for web applications in an LTE mobile communication network is proposed, which takes into account the QoE and service response time.…”

Users expect a high level of application quality without annoying interruptions or delays when using applications in a communication network. This is particularly important in mobile environments where varying channel conditions, user mobility, and interference lead to a variation of the available network resources which ultimately a↵ects application quality. A flexible selection of one or more access technologies, however, allows to overcome resource limitations of one specific access technology. An over-the-top (OTT) virtual access network (VAN) approach allows the aggregation of multiple wireless networks into a single IP pipe to provide users more bandwidth. To minimize energy consumption and radio resource utilization, an application-tailored usage of the access technologies as well as appropriate resource scheduling mechanisms in case of concurrent usage are required. In this paper, we perform a scenario-based investigation of the performance of an OTT VAN architecture. As scenario we choose a user watching a YouTube video clip, while a Wi-Fi and a cellular network are available. We evaluate the user perceived quality, cellular usage, and device power consumption based on testbed measurements.

“…Moreover, their works are only limited to FTP applications without consideration of multimedia services. Some QoE-based VHO algorithms have been proposed in [8,9,17]. The QoEbased VHO algorithms select a target network with the highest predicted MOS that could provide relative good QoE for users.…”

With the advance of wireless technology and popularity of mobile devices, more and more people rely on mobile devices for multimedia services (such as video streaming and video call). A mobile device can be connected and roamed to different networks in heterogeneous wireless networks. The Media Independent Handover (MIH) framework is designed by IEEE 802.21 group to support seamless vertical handover between different networks. However, how to select an appropriate network from available ones and when to execute the handover remain the key challenges in MIH. This paper proposed a user-centric QoEdriven vertical handover (VHO) framework based on MIH that aims to maintain acceptable QoE of different mobile application services and to select an appropriate network based on users' preferences (e.g. on cost). Further a usercentric QoE-driven algorithm is implemented in the proposed framework. Its performance is evaluated and compared with other two VHO algorithms based on Network Simulator 2 (NS2) for video streaming services over heterogeneous networks. The preliminary results show that the proposed algorithm could maintain better QoE and at the same time, take into account user's preference on cost when compared with other two algorithms.
