Abstract

Abstract: The authors of this article have proposed a QoS routing and admission control mechanism QDSR，and have implemented these schemes on a small-scale real-time video transmission testbed.Although the admission control of the QDSR can guarantee enough available bandwidth in every node for all admitted flows passing the nodes，the bandwidth requested by every flow is not guaranteed.Thus，improve QDSR’ admission control mechanism and increase the flow control mechanisms to meet the QoS requirements of real-time applications.Implement the QDSR and above mentioned improvements to QDSR in NS2 simulation environment.The simulation results show that the mechanism improves the transmission quality of QDSR’s video streaming，increases the throughput of the video streaming and the delivery ratio，reduces the end-to-end delay of data packet，And it can be able to well satisfy the transmissions need of a variety of traffic including video applications in wireless ad hoc network.

摘要： 作者曾提出一个QoS路由和准入控制机制－QDSR，并且在小规模实时视频传输实验床上实现了这些方案。虽然QDSR的准入控制只保证每个节点有足够的可用带宽给准入的所有流使用，但并不保证每个流在较小的时间尺度上得到请求的带宽。为此，作者对QDSR的准入控制机制进行了改进并增加了流量控制机制，以满足实时应用的QoS需求。在NS2仿真环境中实现了QDSR以及对QDSR的改进。仿真结果表明，改进机制改善了QDSR的视频流的传输质量，较好地提高了视频流的吞吐率和投递率，减小了数据包的端到端延迟，并且能很好地满足包括视频传输在内的多种业务的传输需要。
