摘要
在研究了多种降低系统功耗方法的基础上,针对无线传感网络的低功耗要求,对无线传感器网络各模块进行了分析和研究,设计并实现了一种基于算法移植的软件开发低功耗的方法,有效降低了节点功耗。采用高性能无线传感器Imote 2节点进行实验,和原有方法进行了对比,并分析其功耗。结果表明:改进后的方法能有效地降低节点的能耗,延长了整个网络的生存期。
Aiming at realizing and designing a low power consumption software development method based on the algorithm transplanting which effectively reduces node power consumption. Aimming at requirement of power consumption of WSNs, each module of the WSNs are analyzed and studied. This method is compared with the original method by using wireless sensors Imote 2 node and power consumptions by both methods are analyzed. The results show that the improved method can reduce the energy consumption of nodes effectively and extend the survival period of the entire network.
