无线传感器网络节点远程升级设计与实现

摘要

Aiming at the difficult situation of Wireless sensor network node upgrade,a solution based on IAP(In Applica-tion Programming)technology is proposed to realize remote upgrade of wireless sensor network node's own program. Combined with existing microcontroller IAPtechnology,wireless sensor network technology and Ethernet,the scheme uses network controller as a core and designs the wireless sensor network nodes supporting IAP and achieves PC soft-ware based MFC for analysis and distribution of firmware files. The test results show that the scheme solves the diffi-cult problem of wireless sensor network node upgrade and has good application prospects.%针对无线传感器网络节点升级困难的现状,提出了一种基于IAP(In Application Programming)技术实现对无线传感器网络节点自身程序实行远程升级的解决方案.方案结合现有的单片机IAP技术、无线传感器网络技术以及以太网,以网络控制器为设计核心,设计支持IAP的无线传感器网络节点,并实现基于MFC的上位机软件用于解析和下发节点文件.测试结果表明,该方案解决了无线传感器网络节点升级困难问题,具有良好的应用前景.
