چکیده
This paper studies effect of packet scheduling algorithms at routers on media synchronization quality in live audio and video transmission by experiment. In the experiment, we deal with four packet scheduling algorithms: First-In FirstOut, Priority Queueing, Class-Based Queueing and Weighted Fair Queueing. We assess the synchronization quality of both intra-stream and inter-stream with and without media synchronization control. The paper clarifies the features of each algorithm from a media synchronization point of view. A comparison of the experimental results shows that Weighted Fair Queueing is the most efficient packet scheduling algorithm for continuous media among the four. key words: packet scheduling algorithm, continuous media, me-

ارزیابی سیاست‌های زمان‌بندی در نسل چهارم شبکه‌های سلولی (LTE)
New generation of wireless networks, LTE and WiMAX, supports many services which consume a lot of resources (such as VOIP, Video Conference, Digital Video, Multimedia streams and online Multi-player Games). Supporting multi-media services in wireless communication systems provide new resource allocation challenges. Because of high loads in downlink, efficient resource allocation is vital in dow...
متن کاملA QoS-Controlled Scheduling Algorithm for Mixed Services in the Downlink of OFDMA Systems
In this paper, we consider a downlink packet scheduling algorithm in OFDMA systems for mixed traffics, such as real-time (RT) and non-real-time (NRT) services. The scheduling algorithm we proposed bases on the Utility Function and the Barrier Function, taking into account the Head-Of-Line (HOL) packet delay and Packet Drop Ratio (PDR) for video streaming. Simulation results show that our new al...
متن کاملImplementing Distributed Packet Fair Queueing in a Scalable Switch Architecture
To support the Internet’s explosive growth and expansion into a true integrated services network, there is a need for cost-effective switching technologies that can simultaneously provide high capacity switching and advanced QoS. Unfortunately, these two goals are largely believed to be contradictory in nature. To support QoS, sophisticated packet scheduling algorithms, such as Fair Queueing, a...

متن کاملThe effect of segmentation mismatch on quality of continuous media transmission by Bluetooth
This paper examines the effect of segmentation mismatch on audio-video transmission by Bluetooth. We focus on the segmentation mismatch caused by the difference between the RFCOMM Maximum Frame Size and the baseband packet payload size. By experiment, we assessed the maximum throughput and media synchronization quality for various types of ACL packets. In the experiment, a media server transfer...
