摘要
ZigBee是一种新兴的无线通信技术,广泛用于自动化、远程监控等领域。由于ZigBee网络中静态路由节点与移动终端节点通信延迟严重,限制了ZigBee的应用,针对此问题提出一种改进的方案。首先简介ZigBee协议栈以及ZigBee网络层,分析现有的Z-AODV协议,并在此基础上提出移动节点快速路由的机制,从而减少通信延迟,实现移动终端节点在静态路由间的平滑无缝切换。
ZigBee is a new wireless communication technology,which is widely used in automation,remote monitoring and other fields.Because there is a serious delay of communication between a fixed node and a portable device in ZigBee networks, which limits the application of ZigBee,this paper proposes an improved mechanism. Firstly,this paper makes a brief introduc- tion of ZigBee Protocol and ZigBee Network Layer,and analyses the original Z-AODV,and then proposes the quick routing mechanism of Portable Devices to reduce the delay and make Portable Devices＂ Smoothly Switching come true.
