Full-view Weak Barrier Coverage Construction Algorithm forWireless Visual Sensor Networks

  • 摘要: 针对利用无线视频传感器网络(WVSN)全视角弱栅栏进行入侵行为检测的问题,建立了一种WVSN全视角弱栅栏覆盖几何模型,采用网格化方法将其离散化,把WVSN最优全视角弱栅栏覆盖问题表示成整数规划形式,并证明其是NP-hard的,进而提出了一个网格厚度优先的WVSN弱栅栏覆盖的启发式算法GTPFWBC。为验证该算法的有效性,进行了大量仿真实验。实验结果显示GTPFWBC算法能较好地解决WVSN的全视角弱栅栏覆盖问题,其全视角栅栏构造成功率明显优于W-GraProj、SP和DP1算法,且生成WVSN栅栏的平均节点数分别比W-GraProj和SP大约节省30.6%和59.4%,另外GTPFWBC的时间复杂度远小于W-GraProj、SP和DP1,因此在能量受限、实时性要求较高的WVSN中GTPFWBC算法的效果更佳。
