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.
