中文摘要：

为了提高无线传感器网络（WSNs）节点能量的利用率,延长WSNs的生存时间,提出了一种单节点的WSNs数据传输优化策略.首先对WSNs结构进行分析,并建立单个传感器节点数据传输优化的数学模型;然后采用惩罚函数法对数据传输过程中的传感器节点能耗进行优化;最后在Matlab 2012平台对其进行仿真分析.结果表明：该方法可以根据环境能量的变化对传感器节点能耗进行自适应优化,提高了节点的累积数据传输总量,可以较好适应环境能量不确定性.

英文摘要：

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. Firstly, 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 carded 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.
