摘要: 随着无线多媒体传感器网络(wireless multimedia sensor networks, WMSNs)的广泛应用,对视频、音频、图像等实时业务的传输提出了更高的要求,要求网络支持服务质量(quality of service, QoS).基于动态源路(dynamic source routing,DSR)协议设计一种支持QoS的路由算法—Q-DSR.该算法可以保证数据流所要求的带宽需求.仿真结果表明,与DSR协议相比,QDSR协议可降低网络时延,提高网络的利用率,满足多媒体业务的QoS需求.

Abstract: With widespread applications of wireless multimedia sensor networks (WMSNs), quality of service (QoS) is required to be supported in the transmission of video, audio and image. This paper proposes a supporting QoS routing algorithm based on the dynamic source routing (DSR) protocol—Q-DSR, which can ensure the bandwidth requirement. Simulation results show that, compared to DSR, QDSR reduces network delay and improves the utilization rate of network, and thus meets the QoS requirement.

Key words: dynamic source routing (DSR), Q-DSR, quality of service (QoS), wireless multimedia sensor networks (WMSNs)
