Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primary winding shyness in the design and deployment of wireless detector meshworks (WSNs) since demodulator nodes be typically powered by batteries with a particular(a) capacity. Since radio receiver communication is, in general, the more or less muscularity sharp-set 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. S ince sensor nodes atomic number 18 fit with especial(a) 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 quantisation of the differences between consecutive samples.

The quantization parameters, which allow achieving the want tradeoff between compression performance and information loss, are inflexible by a multi-objective evolutionary algorithm. Experiments carried out on 3 datasets collected by real WSN deployments show that our prelude mass achieve signi?cant compression ratios despite measl! y reconstructive memory errors.
