“…Similar to TRIANGLE, the experiments are executed in a repeatable and controlled environment. However, in the experiments presented in [13], the user equipment were laptops, which usually have better performance and more resources than smartphones (battery, memory, and CPU). The experiments also evaluated the impact of different scenarios on the multimedia streaming services included in the testbed.…”

This paper presents the TRIANGLE testbed approach to score the Quality of Experience (QoE) of mobile applications, based on measurements extracted from tests performed on an end-to-end network testbed. The TRIANGLE project approach is a methodology flexible enough to generalize the computation of the QoE for any mobile application. The process produces a final TRIANGLE mark, a quality score, which could eventually be used to certify applications.

“…The interaction influence factors provide additional importance, as part of the proposed layered QoE model in multimedia services [7]. Another research has proposed QoE-Lab [8], a multi-purpose heterogeneous testbed, which enables evaluation of scenarios and the correlation of user perceived QoE with the networking conditions. The context-based approach ensures continuous service delivery and consistent quality of experience, by using approach for service and data prefetching from the Cloud.…”

Cloud computing consists of hardware and software resources, available on the Internet as a set of services for users. This technology aims to provide stable, reliable and encapsulated dynamic information and communication environment for end users to be able to simultaneously access shared resources that are available anywhere and at any time. The major benefit of cloud computing is used to improve the perception of quality for the client requests. Commonly in the communications industry, the term Quality of Experience (QoE) is used as a measure for the user perception of service from the user's point of view. In this research, we propose a classification of cloud-based services based on objective and subjective characteristics for perception of quality. The main contribution in this paper is a novel approach based on Bayesian modeling for efficient assessment of QoE perception for cloud-based services considering the level of interactivity, service complexity, usage domain, and multimedia-intensity.

“…To this end, we extend our NGMN VoIP testbed -Mobisense [7] -which already had access to WiFi, UMTS/HSDPA and DSL. We extend its capabilities by adding support for video services and linking it to our other large scale testbed -QoE-Lab [8], which enabled using control mechanisms such as mobility management with Mobile IPv4, network emulation and network monitoring.…”

The evolution of wireless network standards, e.g., GSM/GPRS, UMTS, WiFi, WiMAX, and end-user devices has paved the way towards Next Generation Mobile Networks (NGMN), where users are always connected through multiple radio access networks. NGMN technologies target to improve the user experience especially for mobile data and multimedia services, which are in line with user expectations evident from, for instance, the increasingly popular mobile web video streaming. To understand the quality that can be offered to the user, we compare the Quality of Experience (QoE) for web streaming in a prototype NGMN testbed with WiFi and 3G UMTS/HSDPA support. We use CUBIC TCP as the transport protocol as it is typically the default TCP variant, e.g., in Android phones. We complement the QoE estimations with network Quality of Service (QoS) parameters such as throughput and delay, and transport layer statistics. The results of our evaluation show that (i) video QoE remains stable in WiFi even with high packet loss, (ii) QoE in HSDPA is sensitive to packet loss even for low loss rates due to high variations in the network QoS, namely, throughput and delay, (iii) the decrease in QoE and QoS in HSDPA is due to its negative interactions with the aggressive congestion control of CUBIC TCP, and (iv) handover from WiFi to HSDPA degrades QoE.
