摘要

In wireless sensor networks, clustering is a kind of effective topology control method. It has clear hierarchicalstructure, load balancing, network reliability, strong expansibility and robustness. Currently there have problems in someclustering protocols, such as the clusters distribute unevenly, the selection of cluster heads does not consider the residualenergy and the communication distance deliberately, and the state of clustering does not change with the change of thenetwork 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 thenumber of clusters according to the network states, so that the energy consumption is reduced. The simulation resultsshow that the protocol can prolong the network lifetime significantly, balance the network load, and send more data to thebase station.
