摘　　要：针对传统的无线传感网络数据传递过程中很容易受到外界非线性很强的乘性噪声的干扰,使得在节点选择的过程中,路径计算出现较大的偏差,最短路径的计算准确性不高,降低了无线传感器网络数据传递速度的问题,本文提出了乘性噪声干扰下的无线传感网络优化通信算法,通过准确分析乘性噪声产生的原因,加入反馈机制,对乘性造成干扰下的路径计算进行优化,形成有效地提醒效应,从而避免了传统方式的缺陷。实验证明,优化方式能够提高无线传感网络数据传递的速度,取得了令人满意的效果。In traditional wireless sensor network data transfer process is very easy to get the outside of the nonlinear strong multiplicative noise interference, made in the process of node chooses, path calculation appear larger deviation, the shortest path calculation accuracy is not high, reduce the wireless sensor network data transmission speed. Put forward the muhiplieative noise interference of wireless sensor network communication optimization algorithm, through the correct analysis of the causes of muhiplicative noise, join feedback mechanism to take sex cause interference on the path calculation is optimized, form effective remind effect so as to avoid the defects of the traditional method. The experiment proved that optimization methods can improve the wireless sensor network data transmission speed, satisfactory results have been obtained.
