摘　　要：在无线传感器网络组成的物联网中,受并行通信的干扰,导致多信道信息融合效果差、时延高、信息传送能耗大。为此,提出了针对物联网中无线传感器网络的多信道信息融合方法。通过树型拓扑结构合理分配物联网中传感路由节点信道,抑制并行传感通信的干扰。根据信息熵理论,获取各传感信道信息之间的距离差,采用欧氏距离得出各信息单元的距离熵,进行归一化处理,计算出各传感信息单元属性与融合的权重,按照线性加权算法融合各部分的信息,完成多信道信息融合。仿真结果表明:所提方法的多信道信息融合时延和信息传送能耗始终低于0.69 s和59 J,证明所提方法在传感网络多信道信息融合的效果较好,能够有效降低传感信息融合时延,减小传感信息传送能耗。In the Internet of Things composed of wireless sensor networks,the interference of parallel communication leads to poor multichannel information fusion effect,high delay and high energy consumption of information transmission.Therefore,a multi-channel information fusion method for wireless sensor networks in the Internet of Things is proposed.The channel of sensor routing nodes in the Internet of Things is reasonably allocated through the tree topology structure to suppress the interference of parallel sensor communication.According to the information entropy theory,the distance difference between the information of each sensor channel is obtained.The distance entropy of each information unit is obtained by using the Euclidean distance,and the normalized processing is carried out to calculate the attribute and fusion weight of each sensor information unit.The information of each part is fused according to the linear weighting algorithm to complete multi-channel information fusion.The simulation results show that the multi-channel information fusion delay and information transmission energy consumption of the proposed method are always lower than 0.69 s and 59 J,which proves that the proposed method has a good effect in multi-channel information fusion of sensor networks,and can effectively reduce the sensor information fusion delay and sensor information transmission energy consumption.
