基于WIA-PA的无线网络低功耗设计与实现

Design and Implementation of Low Power consumption Networks Based on WIA-PA

能量问题是工业无线网络设计的一个核心问题;WIA-PA节点通常是通过自身携带能量非常有限的电池供电,而它们工作的环境通常是非常复杂甚至于人类是不可及的,通过更换电池的方式补给能量几乎是不可能的,因此,如何合理高效的使用有限的能量,最大限度的延长WIA-PA网络的生命周期,成为了人们研究的热点;介绍了中国无线工业联盟新推出的具有自主知识产权的WIA-PA技术规范,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,在不影响整体网络性能的基础上延长WIA-PA网络寿命。

Energy problem is very important for routing protocol in WIA-PA Networks since these nodes only rely on their limited battery supply in bad environment.It is not possible for people to replace batteries.So how to make well use of the limited power and prolong the lifetime of the WIA-PA networks became the focus of the people.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.
