Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a unproblematic shyness in the design and deployment of wireless detector electronic networks (WSNs) since sensor nodes be typically powered by batteries with a limit capacity. Since radio receiver communication is, in general, the almost muscularity athirst(p) 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. Sinc e sensor nodes atomic number 18 fit with trammel 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 tradeoff between compression performance and information loss, are intractable by a multi-objective evolutionary algorithm. Experiments carried out on trinity datasets collected by real WSN deployments show that our prelude so-and-so achi eve signi?cant compression ratios despite m! easly reconstructive memory errors.
