Call admission control and traffic policing mechanisms for the wireless transmission of layered videoconference traffic from MPEG-4 and H.263 video coders
نویسندگان
چکیده
In this paper we explore, via an extensive simulation study, the performance of Call Admission Control (CAC) and Traffic policing mechanism proposed for transmitting multiple-layered videoconference movies over a wireless channel of high capacity, depending on the user’s needs and requests. We focus both on MPEG-4 and H-263 coded movies, and in the latter case our scheme achieves high aggregate channel throughput, while preserving the very strict Quality of Service (QoS) requirements of the video traffic.

Pricing-based call admission control for wireless MPEG-4 traffic
Next generation wireless technologies will need to incorporate new sets of traffic control procedures in order to cope with the challenges related to supporting both the existing and the ever-increasing new multimedia services. The work presented in this paper focuses on traffic control for MPEG-4 videoconference over cellular networks, and is twofold. We first introduce a traffic model for med...
متن کاملOn modeling multiplexed VBR videoconference traffic from H.263 video coders
Due to the burstiness of video traffic, video traffic modeling is very important in order to evaluate the performance of future wired and wireless networks. In this letter, we build a highly accurate Discrete Autoregressive model to capture the behavior of multiplexed H.263 videoconference movies from VBR coders. 2007 Elsevier B.V. All rights reserved.
متن کاملImpact of ATM traffic control on MPEG-2 video quality
In this paper, a performance study of controlled MPEG-2 video traffic over an ATM network is presented. ATM networks are able to support variable bit rate (VBR) video sources. However, to implement QoS contract enforcement, traffic policers such as a Leaky Bucket need to be incorporated in order to change the VBR characteristics of a video stream. Our study investigates the video quality achiev...
متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملH.263 Video Transmission in Wireless Local Area Networks using OPNET
Digital video transmission in wireless environment comprises major challenge. Most of the video applications are delay sensitive and have relatively higher bandwidth requirements. Time-varying and asymmetric propagation proOerties of wireless links pose major challenge to low delay and ideally error-free transmission. Studies [1-4] suggest hybrid schemes, optimized control mechanisms or capabil...
