In order to improve energy utilization rate of wireless sensor networks(WSNs) nodes,prolong survival time of WSNs,a new single node data transmission optimization strategy for WSNs is proposed.Firsdy,structure of WSNs is analyzed to establish mathematical model of a single sensor node data transmission optimization;secondly,penalty function method is introduced to optimize energy consumption of sensor nodes in data transmission process;finally,simulation analysis is carried out on Matlab 2012 platform.Results show that the proposed method can adaptively optimize energy consumption of sensor nodes according to change of environmental energy,and improve total cumulative data transmission of nodes,so it can adapt to uncertainty of environmental energy.
