The invention discloses a clustering control method applied to wireless sensor networks and mainly solves the problem that the prior art is poor in reliability and low in adjustability. The method includes: firstly, based on structure of a wireless sensor network, forming original clusters matching with the practical network by non-trivial feature vectors; secondly, estimating the original clusters by increment of network modularity so as to form a cluster structure which is more reliable and more matching with the real network; and thirdly, according to characteristics in practical application of the wireless sensor network, as well as residual energy of nodes and disassortative degree of energy distribution around the needs, selecting a cluster head from each cluster. The wireless sensor network cluster structure built by the method is higher in matching and fine in adjustability, and meets the requirement for reliability of the wireless sensor network cluster structure in severe environmental conditions.
