The invention relates to a node marking method in a wireless Mesh network, including that a first node transmits connection request information; a second node returns to connection response information or selects an undistributed correlation sign to mark the connection relation and return to one connection response information; the first node judges whether the correlation sign is conflicted with a distributed correlation sign or not, if yes, then retransmitting is carried out; the first node or the second node transmits information to a correspondent node; the correspondent node searches a corresponding transmitting node from a local record according to the analyzed MAC address and searches a Mesh node mark; by judging according to the mark, if no bit position is corresponding to the Mesh node mark or the corresponding bit position is set as 'no', which means that no data is transmitted to the correspondent node; otherwise, data is transmitted to the correspondent node.

本发明涉及无线Mesh网络中的节点标识方法，包括第一节点发送连接请求消息；第二节点返回连接响应消息，或者选择一个未分配的关联标志来标识连接关系，返回一个连接响应消息，第一节点判断关联标志与已分配的关联标志是否冲突，如是则重新发送；第一或第二节点向对端节点发送消息；对端节点根据解析出的MAC地址从本地记录中查找对应的发送节点，并查找Mesh节点标识；根据标识进行判断，若没有与Mesh节点标识对应的比特位或对应的比特位设置为&否&，则表示没有要发送给对端节点的数据；否则表示有。
