摘要
介绍了无线传感器网络目标检测基本流程;着重分析了无线传感器网络在实际应用中每个传感器自身存在目标检测范围差异的问题;针对这种情况下的无线传感器网络目标检测问题,提出了一种传感器本地决策阈值的动态算法;最后通过仿真实验,比较了动态阈值算法与其他三种目标检测算法的目标检测误报率。仿真结果表明,提出的动态阈值算法具有较低的检测误报率。
In this paper, the basic scheme of target detection（TD） in wireless sensor network（WSN） is introduced. The problem that each sensor has different characteristic in detecting target is deeply analyzed. In order to solve the problem, a local decision threshold dynamic algorithm is proposed in this paper. As shown in experimental results and practical applications, the algorithm proposed in this paper outperformed the other three TD algorithms to a d^stinguished extent.
