多媒体传感器网络中基于簇的QoS多路径路由协议

Cluster-based QoS multipath routing protocol for multimedia sensor network

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。

A cluster-based QoS multipath routing protocol（CQMRP） is proposed, which is used for multimedia sensor net- work. The network area is divided via fuzzy control clustering algorithm based on local information, on the basis of structure of hierarchical clustering, the protocol takes bandwidth as the QoS parameter, and proposes the concept of node saturation and path saturation, distributes traffic among diverse muhiple path to avoid congestion, and guarantees real-time in data transmission and higher throughput; It uses clustering＇ s hierarchical structure of fuzzy logic to improve the networks scal- ability. The simulation results show that CQMRP has good real-time performance and scalability, it could effectively prolong the network lifetime.
