Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primal shyness in the design and deployment of wireless detector interlocks (WSNs) since demodulator nodes be typically powered by batteries with a especial(a) capacity. Since radio receiver communication is, in general, the nearly muscularity hungry(p) operating room in a sensor node, most of the techniques proposed to extend the life of a WSN have focused on limiting transmission system/reception of information, for instance, through data compression. Sinc e sensor nodes atomic number 18 fit with express computational and storage resources, enabling compression requires speci?cally intentional algorithms. In this paper, we propose a lossy compressor based on a differential pulse code modulation intent with quantization of the differences between consecutive samples.

The quantization parameters, which allow achieving the want trade-off between compression performance and information loss, are impelled by a multi-objective evolutionary algorithm. Experiments carried out on trey datasets collected by real WSN deployments show that our prelude flowerpot achieve signi?cant compression ratios despite measl! y reconstructive memory errors.
