Recent advances in high speed rails (HSRs), coupled with user demands for communication on the move, are propelling the need for acceptable quality of communication services in high speed mobility scenarios. This calls for an evaluation of how well popular voice/video call applications, such as Skype, can perform in such scenarios. This paper presents the first comprehensive measurement study on Skype...
There are many challenges in the QoS controls and traffic handling mechanisms in the deployment of Long Term Evolution (LTE). Simulations are crucial for performance evaluation of end-to-end QoS (Quality of Service) management across LTE network elements over heterogeneous networks. The LTE CoS/QoS Harmonization Emulator presented in this paper will allow the user to determine whether the QoS design...
Performance management (PM) is critical for supporting end-to-end QoS (Quality of Service) across long term evolution (LTE) network elements over heterogeneous networks. In order to effectively deliver QoS traffic from different applications, LTE can be delivered through implementation of logical Class of Service (CoS)/QoS controls in a variety of methods and with variety services. While LTE network...
This paper proposes a video streaming mechanism with packet recovery which extends the Enhanced Adaptive Forward Error Correction (EAFEC) scheme by involving Multiple Description Coding (MDC) with path diversity. The proposed mechanism transmits multiple video sub-streams along multiple disjoint paths, then recovers the sub-streams using EAFEC separately, and at last merges and reconstructs the whole...
