A huge amount of mobile traffic runs on Internet every day. The complex mobile traffic data may degrade the network performance if they are not well managed. As the important foundation of network management, mobile network traffic classification aim to map IP packets into a predefined traffic class set. Most work in this area until now has focused on classification schemes. In contrast, little attention...
Mobile web traffic analytics helps mobile network operators to understand subscriber behaviors and network characteristics. With the increasing prevalence of mobile devices, people are prone to access Internet by mobile devices. Meanwhile, a large amount of applications and services are being moved to the mobile web. These changes have resulted in the elevated complexity of mobile web traffic. Consequently,...
The network-centric CAC schemes try to do resource reservation into networks for mobile connections, observing network status only. This approach can be appropriate for non-real time traffic, but for real-time applications, hasn't showed good results. In this paper, we introduce the PI-CAC, a user-centric L3 CAC scheme, based on user quality of experience for integrating WLAN and 3G networks, with...
In this paper we study the impact of various parameters on the user perceived quality of video transmission over mobile ad hoc (MANET) networks. These parameters include the obstacles coverage area in the MANET deployment area, the nodes' mobility speed and the background traffic. The simulated results have shown that the performance of the perceived video is severely affected as the number of the...
Multimedia social network analysis is an emerging research area, which analyzes the behaviour of users who share multimedia content and investigates the impact of human dynamics on multimedia systems. In collaborative mobile networks, receivers cooperate with each other to provide a distributed, highly scalable and robust platform for live streaming applications. However, every user wishes to use...
In this paper, we propose a new architecture for optimizing the traffic of video streams in wireless mobile environments by providing environmental information locally to the application running on each mobile node. With such information, the application can adapt the quality of video streams.
Mobile WiMAX aims to provide multimedia multicast/broadcast service (MBS) as well as elastic data service. However, supporting delay sensitive applications like video/audio streaming is still challenging, which requires both efficient handling of link bandwidth and reducing handover delays. To reduce the handover delay in MBS, the IEEE 802.16e standard defines an MBS zone, which is a group of base...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
