The distributed clustering method is widely used to extend network lifetime in traditional wireless sensor networks. However, it is difficult to achieve the idea performance of the whole network, such as transmission rate, energy consumption, and control overhead, neglecting the global stability of the network. To tackle this problem, a centralized mobility-based clustering (CMBC) protocol is proposed in the software defined sensor network. The method of CMBC mainly consists of two aspects: first, CMBC clusters the nodes with the connection time between the mobile nodes (i.e., noncluster head nodes, non-CH) and the cluster head (CH) and establishes stable topological structures between the non-CHs and the CH; second, when emergencies occur, the centralization management control center sends the configuration files to replace the CH. Compared to the distributed network of MBC, WCRA and IMP-MECA protocol, the proposed method can be applied in scenarios with high-speed mobile nodes to improve the network performance in terms of transmission successful rate, average power consumption, and average control overhead.

分布式群集方法被广泛用于延长传统无线传感器网络中的网络寿命。但是，难以实现整个网络的思想性能，例如传输速率，能耗和控制开销，而忽略了网络的全局稳定性。为了解决此问题，在软件定义的传感器网络中提出了基于集中式移动性的群集（CMBC）协议。CMBC的方法主要包括两个方面：首先，CMBC将节点与移动节点（即非群集头节点，非CH）和群集头（CH）之间的连接时间进行群集，并在非节点之间建立稳定的拓扑结构。 -CH和CH；其次，当紧急情况发生时，集中管理控制中心发送配置文件替换CH。
