This paper studies chaos synchronization-based data gathering scheme in wireless sensor networks with multiple sinks. In the proposed scheme, each wireless sensor node has a simple chaotic oscillator. The oscillators generate impulsive signals with chaotic interspike intervals, and are impulsively coupled by the signals via wireless communication. Each wireless sensor node receives and transmits sensor information only in the timing of the couplings, and turns off own power supply in the other timing. The proposed scheme can exhibit various chaos synchronization, and can effectively gather sensor information with low energy consumption. Also, the proposed scheme can flexibly adapt various wireless sensor networks not only with a single sink node but also with multiple sink nodes by dynamically changing the network topology. We evaluate the proposed scheme using computer simulations. Through simulation experiments, we show effectiveness of the proposed scheme and discuss its development potential.
