The invention discloses a quick repair method of Zigbee wireless sensor network, belonging to the wireless network technical field. The present invention through each terminal node of a node can record the beacon information set in the network in the parent node record table; the terminal node in the first to join the network, to conduct a complete channel scan, the number of beacon channel until all has been scanned or received to the end of the scan; the terminal node record these beacon information, and related record from the parent node selects a node; the beacon frame table and all nodes in the tracking terminal node periodically, the node of the new beacon information on the old letters and continue to use the received information update; when the terminal node finds itself has become acnode delete the current beacon information equipment, the parent node from the table, and then directly from the table to select a node re association. The method of the invention can shorten the network repair time and improve the network repair efficiency. ?
【技术实现步骤摘要】
【技术保护点】
一种Ｚｉｇｂｅｅ无线传感网络快速修复方法，该网络为Ｚｉｇｂｅｅ树型信标网络，包括三种节点：协调器节点、路由器节点和终端节点，协调器节点和路由器节点以不同的周期发送信标，告知终端节点自身的情况，终端节点利用信标与协调器或路由器进行时间同步并进行通信，其特征在于，所述方法包括：该网络中每一个终端节点存在一个父节点记录表，可记录Ｌ↓［ｍａｘ］个节点的信标信息，Ｌ↓［ｍａｘ］为预先设定的大于１的自然数；终端节点在首次加入该网络前，先进行一次完整的信道扫描，直到所有的信道都被扫描或接收到的信标帧数目达到Ｌ↓［ｍａｘ］时结束扫描；终端节点记录这些信标信息，并从父节点记录表中选择一个节点进行关联，该节点称为当前父节点，表中的其余节点作为备用父节点；终端节点周期地跟踪表中所有节点的信标帧，并不断地用接收到的新信标信息对表中节点的旧信标信息进行更新；当终端节点发现自身已经变成了孤点设备，则从表中删除当前父节点的信标信息，然后直接从表中选择一个节点进行重新关联。
