| 摘 要： | 提出一种ad hoc网络中新的簇结构模式。采用约束特征值的概念对ad hoc网络中节点移动的约束环境进行数学抽象，定义了节点属性的数学表达式。以节点的通信能力值和状态变化值作为选择簇头节点的依据，在此基础上提出了分簇算法GM-BFS，对平面ad hoc网络进行分簇，最后使用偏移度概念实现节点在簇间的移动和动态切换。

| Abstract: | A new clustering model for wireless ad hoc network is presented The metric of constraint degree is used to describe the mobility condition of nodes in the network, and a mathematical expression is defined based on attributes of the node The clusterheads are selected according to communication capability and state transition of the nodes, and the clustering is performed using the GM BFS algorithm The handoff problem of mobile nodes is handled by the offset degree finally |
