摘要
对自组织ZigBee网络的原理进行了研究,并抓住其精髓进行了剖析,给出了自组织ZigBee网络节点通信流程和软件流程。自组织ZigBee网络每个节点只和其邻近节点通信,从一个节点发出的数据包将根据相关协议的配置多跳传递到目的节点。网络中的每台设备都可直接通信,或者通过网络的转发而连接到其他设备。每个网络节点都具有选路功能,如果其中的某一条链路出现了故障,节点便可以自动转向其他可选链路进行接入,因而减轻了业务执行时发生冲突的可能性。自组织ZigBee网络的研究,对网络中的资源节俭,网络的维护与操作,升级与扩容有着指导意义。
The principle of self-organizing ZigBee networks is studied and analyzed, the flow chart of node communication and software of self-organizing ZigBee network is given. Each node of the network makes communication only with its adjacent node, and the date-packet sent by each node in accordance with the agreement of the relevant multi-hop configuration is delivered to the destination node. Each equipment of network could make direct communication, or through network forwarding, is connected to other devices. Each network node has its routing function, and if a link fails, the node would automatically turn to other available links for access, thus reducing the conflicts. The study on self-organizing ZigBee network, could give a guide for resources saving of network, network maintenance and operations, expansion and upgrading.
