摘　　要：无线视频传感器节点能量有限,为减小其能耗,延长网络生存时间,提出了一种多角度改进优化的视频传感器网络通信协议MSOWVRP。首先对传统技术的不足进行分析,结合相关性感知、虚拟势场等概念从簇首节点的选择、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平台上进行了仿真对比测试。仿真结果表明,MSOWVRP协议能够提高传感器网络生命周期和监测区域覆盖率。Node energy in wireless video sensor networks is limited, in order to reduce energy and prolong network lifetime, an improved novel outing protocol based on multi angle in video wireless sensor networks was proposed in this paper. Firstly, the topical routing protocol of wireless video sensor networks was analyzed to find the defects, secondly, head node selection and cluster formation, the node sensing direction adjustment, cluster communication were improved and optimized, finally, the simulation experi- ments were carried out to test the performance. The results show that our proposed outing protocol can prolong network lifetime and improved coverage rate of monitoring.
