This paper proposes and analyzes a bio-inspired scheme to field estimation using wireless sensor networks. The proposed scheme exploits the temporal pattern of the sensed process to reduce the number of samples sent back by a sensor node to the sink and decrease the energy consumption in data transmission. The proposed scheme is orthogonal to the techniques that reduce the spatial density of collected samples desactivating nodes with similar measurements. Thus, the proposed scheme can be used along with these techniques.
