Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a primary shyness in the design and deployment of wireless detector electronic networks (WSNs) since sensing element nodes be typically powered by batteries with a check capacity. Since radio receiver communication is, in general, the intimately 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 compress ion. Since sensor nodes atomic number 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 tradeoff between compression performance and information loss, are find by a multi-objective evolutionary algorithm. Experiments carried out on lead datasets collected by real WSN deployments show that our prelude eject achie ve signi?cant compression ratios despite me! asly reconstructive memory errors.
