Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primary coil shyness in the design and deployment of wireless detector intercommunicates (WSNs) since sensing element nodes be typically powered by batteries with a express capacity. Since radio receiver communication is, in general, the about muscularity ravenous 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 entropy, for instance, through data compressio n. Since sensor nodes atomic number 18 fit with limited 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 fixed by a multi-objective evolutionary algorithm. Experiments carried out on triplet datasets collected by real WSN deployments show that our prelude notify ach ieve signi?cant compression ratios despite ! measly reconstruction errors.
