In this paper, TA-ARQ (Time-constrained Aggregated Automatic Repeat-reQuest) with an adaptive rate control for SVC streaming based on HDP transport protocol is proposed. To meet the requirement of terminal equipment in the heterogeneous network environments, we consider SVC for different applications. Selected NALUs (Network Abstraction Layer Units) are sent according to the quality estimation of...
Quality of Service (QoS) is considered as the standard check of a conveyance system to show provided services and its availability. For illustration application like video conferencing, voice over ip (VOIP), streaming videos, real time operation feel necessity for draconian assurance on jitter, packet loss, prioritization of services and end-to-end delay. So to overcome these issues a novel scheme...
When a mobile host transmitting real-time video traffic using DCCP CCID3 moves between two wireless LAN access points with different congestion situations, it is difficult to quickly change the transmission rate according to the changes of communication environment because controlling the sending rate depends on feedback information. To solve this problem, we recently proposed a predictive rate control...
The explosive demands of multimedia services have been grown up to support delay-sensitive applications, e.g., VoIP and streaming using codec. When a mobile node (MN) moves across different types of networks, the codec should be effectively adapted according to the significant change of network condition, i.e., throughput and delay. Therefore, in this paper, we propose a codec adaptation for vertical...
Goal of the reported experiment was to determine in which way wirelessly transmitted video streams influence each other. Former experiments gave the impression that the behavior of video streams is unpredictable, e.g. due to unstable play-back and uncertain starts. To transport two video streams simultaneously over a wireless/wired network, the video servers use different network protocols (TCP and...
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...
