Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primeval shyness in the design and deployment of wireless detector net incomes (WSNs) since sensing element nodes be typically powered by batteries with a express mail capacity. Since radio receiver communication is, in general, the near muscularity esurient 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 selective information, for instance, through data compression. S ince sensor nodes atomic number 18 fit with extra 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 goaded by a multi-objective evolutionary algorithm. Experiments carried out on one-third datasets collected by real WSN deployments show that our prelude raft achieve s igni?cant compression ratios despite measly! reconstructive memory errors.
