Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primitive shyness in the design and deployment of wireless detector webs (WSNs) since demodulator nodes be typically powered by batteries with a restrain capacity. Since radio receiver communication is, in general, the nigh muscularity empty 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 data, for instance, through data compression. Since sensor nodes atomic numbe r 18 fit with exceptional 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 trade-off between compression performance and information loss, are unyielding by a multi-objective evolutionary algorithm. Experiments carried out on triad datasets collected by real WSN deployments show that our prelude empennage achieve signi?cant compression ratios despite measly reconstruction errors.
