摘　　要：针对ZigBee底层依赖的IEEE 802.15.4标准,通过分析其组网连接流程,采用Jennic无线芯片实现,并在研究分析入网时延的基础上提出了一种基于802.15.4标准最大化缩短设备入网时延的实际应用方案,该方案下入网时延缩短为标准流程下的十分之一并很大程度地削减了多节点下冲突所带来的入网时延上的影响.IEEE 802.15.4 is the mac-protocol which is applied in ZigBee technology. The network association process is analysised. Network is designed using Jennic wireless chip based on analysis delay of network association, a novel practical application is proposed on IEEE 802. 15.4 standard, which sharply shortens the time delay of network association. The time delay is shortened as one-tenth of the standard process, and effect of Multi-node collision is extent reduced.
