随着无线传感器网络（WSN）的广泛接受，该网络有望应用于庭院和花园的环境测量。由于环境测量中无法获得稳定的电力供应，无线传感器网络一般采用电池供电。为了延长无线传感器网络的运行时间，提高能源效率非常重要。另一方面，在实际的环境测量中，传感器的值没有显着变化，并且相邻传感器在稳定条件下指示相似的值。本研究提出群控制方法作为一种新的节能技术。该方法利用相邻传感器之间的值的相似性和环境测量中的时间稳定传感器值。该方法形成传感器组并调整网络节点的休眠时间以降低功耗。本文基于仿真评估展示了功耗和传感精度的有效性。
As Wireless Sensor Network (WSN) has been widely accepted, the network is expected to be applied to environmental measure in yards and gardens. Because stable electric power supply is not available in environmental measure, WSN is generally powered by battery. Improving energy efficiency is important in order to extend operation time of WSN. On the other hand, in actual environmental measure, values of sensors do not vary significantly, and neighbor sensors indicate similar values in stable condition. This research proposes Group Control Method as a new power-saving technique. This Method utilizes the similarity of the values among neighbor sensors and time-stable sensor value in environmental measure. The method forms sensor groups and adjusts sleep time of the network nodes to reduce power consumption. This paper shows effectiveness of power consumption and sensing accuracy based on simulation evaluation.
