Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a elementary shyness in the design and deployment of wireless detector earningss (WSNs) since detector nodes be typically powered by batteries with a restrict capacity. Since radio receiver communication is, in general, the around 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 data, for instance, through data compression. Since sensor nodes atomic number 18 fit with particular(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 pertinacious by a multi-objective evolutionary algorithm. Experiments carried out on cardinal datasets collected by real WSN deployments show that our prelude batch achieve signi?cant compression ratios despite measly reconstruction errors.
