A topology control system and a corresponding topology control method for dynamic network is provided. The topology control system for dynamic network includes a sensing module, a data processing module, a data judgment module, a communication module and a central module. The sensing module collects the data of the surrounding nodes, and transmits it to the data processing module for caching, and then selects the cluster head of the current node according to the data, and then transmits it to the data judgment module. After the data judgment module checks the cluster head qualified, the communication module is responsible for wireless transmission of cluster head information to the central module. The central module collects the data of all nodes in the network and transmits the results to the client. It can be used for topology control of the dynamic network.
