摘　　要：在传感网中如果2棵以Sink节点为根节点的生成树使得网络中任意源节点在这2棵树上到Sink节点的路径没有相交节点,称这2棵树为该网络的ND(Node Disjoint)树。针对工业无线传感网的应用需求与特点,研究了基于ND树的路由方案。仿真实验和分析表明,该路由方案具有较高的路由可靠性。针对该路由方案的特点与需要,给出了1种节点二连通(Two-node-con-nected)网络的部署方案。If two spanning trees with the sink node as root make the paths from any given source node on the two trees to the sink node are node-disjoint, they will be termed as Node Disjoint （ND） trees. Aiming at the requirements and features of industrial wireless sensor networks, this paper studies the routing schemes based on ND trees. Analysis and simulation show that the proposed routing scheme can achieve higher reliability and lower packet delivery delay. Besides, a scheme to deploy two-node-connected networks is also presented.
