摘　　要：笔者在各传感器之间有一个衰落的无线通道和融合中心(Fusion Center,FC)的前提下,提出了一种基于泊松点过程的无线传感网络分布估计方法。首先描述了空间上随机的无线传感网络统计特性,推断出在不同信道状态信息的情况下,优化融合中心所产生的中断性能。其次,结合路径损耗分析了无线传感网络的性能。最后,扩展分析了传感器噪声测量情况。仿真结果验证了提出的分析法的可行性和可靠性。Under the premise that there is a fading channel between the sensors and the fusion center(Center Fusion,FC),the author proposed a distributed estimation scheme for wireless sensor networks based on homogeneous Poisson point process.In this passage,the statistical characteristics of stochastic wireless sensor networks in space are described firstly,and then the outage performance of the fusion center is optimized under the condition of different kinds of channels.After analyzing the performance of wireless sensor networks combined with pass loss,the measurement of sensor noise is extended.The simulation results verify the feasibility and reliability of the proposed method.
