摘要 通过分析树形无线传感器网络的工作原理,引入反馈结构。在一个可能产生信道噪声的网络中,每个节点在进行判决时会综合考虑自身在上一时刻的判决与自己所有子节点的判决。通过这样的反馈结构利用更多的信息进行判决,从而降低信道噪声对系统检测性能的影响。实验与分析表明,该算法可以提高系统的检测性能。 By analyzing the working principle of the tree-shaped wireless sensor network,the feedback structure is introduced in this paper.In a network that may generate channel noise,each node will comprehensively consider its own decision at the previous moment and the decision of all its child nodes when making a decision.Through such a feedback structure,more information is used to make a decision,thereby reducing the influence of channel noise on the detection performance of the system.Experiments and analysis show that the algorithm can improve the detection performance of the system.
