Abstract: Some of the existing topology generation algorithms need node location in general，which not only increase the complexity of the algorithm and node energy consumption，but also can not make a very good balance of energy and nodes degree.This paper proposes a new kind of rain-clustering algorithm simulating raining process.In the raining，rain hitting on the ground produces the sprays of the rain and forms waves.Using the so-called rain-clustering algorithm achieves the targeted wireless sensor networks without the support of node location operation，and makes the node degree balance and suitable uses of the node energy.

Key words: wireless sensor networks, clustering algorithm, node energy, node degree
