节能已经成为无线传感器网络研究的核心部分。该文研究了无线传感器网络拓扑结构的邻近节点数对网络能耗的影响，主要采用动态电压调节技术（DVS）来降低无线传感器网络中节点的能耗。动态电压调节主要通过减少门等效电容、供电电压以及降低转换因子、时钟频率来达到降低动态能耗的目的，其中，降低供电电压节能效果最佳。与其他方法相比，动态电压调节降低能耗更加明显、效率更高。通过在CC2430节点芯片上测试验证，通过改变其分频比，得出了功耗和频率的近似线性关系。

Currently,energy conservation has become a core part in research of the wireless sensor network. The effect of number of neighboring nodes in wireless sensor network topological structure on network energy consumption is studied in this paper. The dynamic voltage scaling(DVS)technique is adopted to reduce energy consumption in nodes of wireless sensor net?work. Low dynamic power consumption is achieved primarily by dynamic voltage regulation which can reduce the gate equivalent capacitance,power supply voltage,conversion factor,clock frequency,in which reduction of the supply voltage is the most im?portant one for energy saving. Compared with other methods,dynamic voltage scaling is even more obvious and more efficient for reducing energy consumption. The approximately linear relationship between power and frequency was obtained by changing the frequency division ratio of CC2430 chip in its testing and validation.
