The MONROE testbed enables the objective performance assessment of Mobile Broadband (MBB) networks from the end-user perspective, using highly distributed measurements from fixed and mobile nodes. To quantify the performance of MBB networks for popular Internet services from a user-centric perspective, dedicated tools are needed. In this paper we extend the MONROE testbed to the Quality of Experience...
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...
Increasing usage of OTT (Over-the-top content) and IPTVservices on mobile broadband access networks leads us to find out content aware QoS mechanisms on new generation mobile core networks. SDN/NFV is key technology for future generation mobile networks. Cellular core network functions can be virtualized and programmable with SDN/NFV approach. In this work we discuss SDN/NFV based QoS mechanism based...
Over the last few years, the number of remote patient monitoring (RPM) products and of videoconferencing systems has exploded. There is also a significant number of research initiatives addressing the use of service robots for assistance in daily living activities. From a technological standpoint, providing telehomecare services is certainly feasible. However, one technological barrier is to have...
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...
It is important for network operators to know how users use the network to plan and design network facilities. In this paper, we propose flow classification method using binned time-series data in consideration of practicality. In this paper, we evaluate the proposed method by using mobile data traffic and show the method can maintain classification accuracy as compared with method using the whole...
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...
This paper presents a Laboratory of Remote Access education, being the object of study UAV — Unmanned Aerial Vehicle internet that can be used for courses in Aeronautical Engineering. Through a ground station mobile, you can remotely piloting UAVs, capture video images through cameras shipped, and determine their geographical position of the region monitored in real time. Basically, the ground station...
Using Peer-to-Peer technology to deliver live video streams to mobile devices is a promising approach. It allows service providers to scale their video distribution without increasing their cost. As the resources are replicated at the edge of the network, mobile devices can take advantage of close-by peers in order to get the required data faster. This, however, is challenging due to the highly dynamic...
The idea of this research is for the concern of Collaborative learning based mobile factors. We focus on three features, computer mutual learning, learning process module, and student learning mode. In this paper, student-focused instruct module. student edge section, teacher interface section, learner section. solution problem section, curriculum section, control section, and diagnose section are...
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...
The current content provision methods and associated pricing and business models are challenged by the traffic requirements anticipated for future “data intensive” services. In order to deliver substantially higher peak rates operators will need to deploy a much denser infrastructure and/or acquire more spectrum, thus significantly increasing their CAPEX and OPEX and reducing revenues. To improve...
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...
YouTube and Facebook are two of the most consumed applications in today's Internet. Together they account for more than 30% of the overall Internet's traffic volume and span more than half of the Internet users worldwide. Such popularity has attracted a growing interest from the research community, particularly regarding content characterization, network performance, and privacy issues in these applications...
This paper based on embedded technology, video coding compression technology, GPRS mobile communications technology and so on. Design a video monitoring system of embedded wireless remote mobile. The front end hardware platform choose S3C2440 chip of SAMSUNG company as MCU.GPRS wireless module to send data. The software platform choose embedded Linux operating system. Construct the module of video...
We developed a prototype system for supporting presentation with a mobile PC in distance education, which have been designed to keep eye contact between students and a lecturer and to facilitate finger pointing by a lecturer in videoconference. Despite convenient functions supporting videoconferencing, it is often difficult to keep the awareness and attention information during remote lectures. Our...
An existing network video monitoring system has already realized putting independent video sources online, to monitor, manage and share resources in unison, in use of IP-based network. With the popularization of wireless network, system should resolve the bandwidth bottleneck in order for good of support for wireless video's uploading technology. So as to improve user experience, it is very important...
The objective of Mobile video monitoring system is to provide high performance low latency video streaming to the client side. This work presents an effective system design and implementation for mobile video monitoring. We focus on the whole system design and some key issues on video encoding and decoding. We compare our design to existing solutions and experiment results demonstrate the efficiencies...
