无线视频传感器网络（ WVSNs）节点的能量十分有限，为了降低传感器节点的能耗，延长网络生存时间，提出了一种基于相关性感知的视频传感器网络通信协议。首先对当前经典无线视频传感器网络路由协议的不足进行分析；然后从簇首节点的选择、簇的形成、节点感知方向的调整、簇内通信以及簇间通信等几个方面进行改进和优化；最后在Matlab 2012平台进行了仿真对比测试。仿真结果表明：该协议不仅能够延长无线视频传感器网络生命周期，而且提高了监测区域覆盖率。

Node energy in wireless video sensor networks(WVSNs)is limited,in order to reduce energy consumption and prolong network lifetime,a novel communication protocol based on correlation-aware in WVSNs is proposed. Firstly,current typical routing protocol of WVSNs is analyzed to find the defects;secondly,cluster head node selection,cluster formation,and node sensing direction adjustment,communication within and inter cluster are improved and optimized;finally,simulation and comparison test are carried out on Matlab 2012 platform. Simulation results show that the proposed protocol can not only prolong network lifetime but also improve coverage rate of monitoring area.
