摘要 无线视频传感器网络(WVSNs)集成了视频传感器、计算机、通信三大技术,是当前国际上的一个研究热点。介绍了WVSNs的结构,并针对网络的QoS问题进行了分析,随后针对网络的QoS需求,综合考虑传感器节点能量、输出码率、传输时延、信道差错率和数据失真等因素,设计了一个提供QoS保证的传输模型,并对常见的QoS路由协议进行了比较。 Wireless video sensor networks(WVSNs)which integrates three technologies—video sensors,computers and communication technologies,is currently a hot topic in the world.The structure of WVSNs is introduced.The QoS problems aiming at networks are analyzed.Aiming at the QoS demand for networks,considering the energy of sensor nodes,the output bit rate,transmission time delay,channel error rate and data distortion,a transmission model is designed to provide QoS guarantee.Common QoS routing protocols are compared.
