Congestion control is vital in the streaming of a video sequence or clip, as network traffic varies unpredictably requiring constant adjustment of the transmission rate. Standard TCP-Friendly Rate Control (TFRC) wastes bandwidth and may react to congestion only when packet loss has already occurred. This paper presents a unicast transport protocol named RRB-SIMD for video streaming over the Internet,...
The bandwidth in wireless networks is usually shared by a number of wireless nodes. The channel capacity depends on the number of accessing nodes, time, environmental conditions and location of nodes. Due to varying channel conditions, several issues are observed in the transmission of real time multimedia. The existing research on multimedia streaming can be classified into adaptation techniques...
In this paper, we propose a new variant of TCP with an early retransmission scheme as an enhancement to make it more suitable for streaming media. We call this new protocol TCP-ER. We performed extensive ns2 simulations to show that: 1) The early retransmission scheme can considerably reduce the number of retransmission timeouts and packet delay jitter in a variety of network environments. 2) TCP-ER...
Today, as the Real-time Transport Protocol (RTP) is used more and more widely in the streaming media services such as real-time video in the internet. The algorithm of RTP adaptive transmission control is an important factor to guarantee the quality of video transmission services. So, much more attention should be paid to the research on the algorithm. In this paper, on the base of researching on...
We analyze and compare various transport protocols in the context of wireless in-vehicle IP-based audio and video communication. We determine the most appropriate transport protocol and discuss its benefits for an application in the car. The analyses are accomplished based on the IEEE 802.11 standard. A testbed is used to measure and compare quality of service values such as throughput, jitter and...
