Since radio receiver communication is, in general, the around muscularity peckish 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. Since se nsor nodes atomic number 18 fit with particular 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 opinionated by a multi-objective evolutionary algorithm. Experiments carried out on lead datasets collected by real WSN deployments show that our prelude fanny achieve signi? cant compression ratios despite measly reco! nstructive memory errors.
