集群式多媒体监控系统QoS管理模型

Considering characters and requirements of the Cluster Surveillance and Control System, the networktopology structure of the system is presented and the hiberarchy model of QoS management is studied. Based on theCORBA technology, an effective resources management and quality guarantee system is completed. It is used formanaging resources in each point of the system and ensuring the quality of services.

多媒体传感器网络中基于簇的QoS多路径路由协议

针对多媒体传感器网络的应用,提出了一种基于簇的服务质量(quality of serve,QoS)多路径路由协议(cluster-based QoS multipath routing protocol,CQMRP),利用本地信息采取模糊控制的分簇方法对网络进行划分,然后在分层分簇的网络模型基础上,以带宽为QoS参数并提出节点饱和度和路径饱和度的概念,利用多路径并行传输流量实现拥塞避免、数据实时性传输和网络的高吞吐量;利用模糊控制的分簇方法实现网络的层次化管理和提高应用的可扩展性。仿真结果表明,该协议具有良好的实时性和可扩展性,并能有效延长网络生命周期。
