In wireless sensor networks, clustering is a kind of effective topology control method. It has a clear hierarchical structure, load balancing, network reliability, strong expansibility and robustness. Currently, there have problems in some clustering protocols, such as the clusters distribute unevenly, the selection of cluster heads does not consider the residual energy and the communication distance deliberately, and the state of clustering does not change with the change of the network states. In order to resolve these problems, we design a Virtual Coordinates Dynamic Adaptive Clustering protocol (VCDAC). The protocol divides the network into clusters according to the idea of virtual partition and decides the number of clusters according to the network states, so that the energy consumption is reduced. The simulation results show that the protocol can prolong the network lifetime significantly, balance the network load, and send more data to the base station.
