摘要
该文介绍了基于802.15.4标准的WIA-PA工业无线网络,并分析了网络节点能耗情况,提出相应的节能策略。将节能策略引入到网络研发中,从硬件和软件两个方面来降低网络节点的能量消耗,在保证网络可靠性的基础上尽量延长WIA-PA网络生存时间,最后对节点进行性能测试。实验结果表明,该方法有效地节约了网络能量,对WIA-PA网络的设计与实现具有一定的借鉴与指导作用。
This paper introduces the WIA-PA criterion from the wireless industrial networking alliance of china and analyses the energy depleting from hardware design to software design without affecting the performance of the WIA- PA networks. At the end of the paper we presented a test about the performance of node hardware. The results of test show that the method effectively saves the energy of network, and it will be guidance for the design and implementation of WIA-PA network.
