YoMoApp (YouTube Monitoring App) is an Android app to monitor mobile YouTube video streaming on both application- and network-layer. Additionally, it allows to collect subjective Quality of Experience (QoE) feedback of end users. During the development of the app, the stable versions of YoMoApp were already available in the Google Play Store, and the app was downloaded, installed, and used on many...
In this work, we propose an adaptive congestion control and avoidance mechanism as an enhancement to our earlier proposed QoS-aware routing protocol. We utilize Ant Colony Optimization (ACO) algorithms for adaptive multipath routing and use the monitoring feature of the Simple Network Management Protocol (SNMP) for QoS computation. So, merging these two methodologies we propose a powerful adaptive...
With the increasing adoption of mobile 4G LTE networks, video streaming as the major contributor of 4G LTE data traffic, has become extremely hot. However, the battery life has become the bottleneck when mobile users are using online video services. In this paper, we deploy a real mobile system for power measurement and profiling of online video streaming in 4G LTE networks. Based on some designed...
This paper provides a brief overview and a vision for introducing a Quality of Experience (QoE) function for on-demand services or for premium users, based-on Software-Defined Networking (SDN). The proposed “QoE-service” can take advantage of the SDN global resource view and complementary QoE metrics to assure the desired performance for OTT applications by adopting traffic management mechanisms....
In recent years, the monitoring of End-to-End protocols from inside the mobile data network has become a powerful tool to gain insight into subscriber specific information on usage behavior and quality of experience. With the advent of big data in mobile networks, the power of statistical data analysis can now be utilized in order to answer so far untreatable questions both in the area of network...
Real-time entertainment constitutes the majority of traffic in today's mobile networks. The data volume is expected to increase in the near future, whereas the mobile bandwidth capacity is likely to increase significantly slower. Especially peak hour traffic often leads to overloaded mobile networks and poor user experience. This increases costs for the mobile operator, which has to adapt to the peak...
Reducing operational costs and increasing energy efficiency are critical for mobile operators. One accepted way to tackle these issues is to make use of virtualization to share the same physical infrastructure among several virtual networks. However, sharing physical infrastructure presents a number of challenges, such as security issues, conflicting hardware control, and fair resource sharing. In...
YouTube, the killer application of today's Internet, is changing the way ISPs and network operators manage quality monitoring and provisioning on their IP networks. YouTube is currently the most consumed Internet application, accounting for more than 30% of the overall Internet's traffic worldwide. Coupling such an overwhelming traffic volume with the ever intensifying competition among ISPs is pushing...
Due to the explosion of various video applications and services it is becoming increasingly important to accurately measure video quality in real-time. Since reference information is absent in many practical situations, video quality assessment with No-Reference (NR) measures is attracting increasing attention from both industry and academia. However, there are very few commercial quality assessment...
This paper proposes a mobile phone integrated alarming-system, which has two models: mobile, fixed alarm-ways. The alarming information contains local sound, video and GPS information. The system provides two ways of reading the alarming information: web ways and mobile alarming media player ways for instant checking or repeated watching and analysis .The real-time transmission of sound and video...
Dynamic spectrum management (DSM) is a key feature for enhancing cooperation in wireless video sensor network (WVSN) towards supporting communication of high data-rate video information. Unlike traditional spectrum allocation, DSM in WVSN should have topology control and distributed control center. In this paper, we propose an ILST algorithm for constructing distributed DSM topology control with the...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
