基于WIA-PA的工业无线网络节能设计与实现

在能量有限条件下通过降低能耗来延长网络生存时间是工业无线网络面临的重要挑战之一。WIA-PA网络要求使用能量有限的电池供电,能适应条件和环境的动态变化,保持网络的可靠和稳定,并能够在低成本且低功耗的商用器件上实现,从而降低技术开发与实现难度,便于用户以较低的投入换来易于使用和维护的工业无线测控系统。本文介绍了中国具有自主知识产权的WIA-PA技术,并从硬件设计和软件设计两个方面来降低网络节点的能量消耗,在不过多影响整体网络性能的基础上延长WIA-PA工业无线网络的寿命。

Energy-Saving Design and Implementation of Industrial Wireless Networks Based on WIA-PA

Reducing power consumption to extend network lifetime with limited energy resource is one of the most important challenges in industrial wireless networks. WIA network requires limited energy resource, adapts dynamic surroundings and keeps the reliability of the network. Aiming at low power consumption and cost, 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.
