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 res...
