A Multi-Objective Evolutionary Approach To Data Co

2009 Ninth International Conference on Intelligent Systems radiotherapy pattern and Applications A Multi-objective Evolutionary Approach to Data coalescence in Wireless Sensor Networks Francesco Marcelloni Dipartimento di Ingegneria dellInformazione University of Pisa Via Diotisalvi 2, 56122 Pisa - ITALY f.marcelloni@iet.unipi.it Massimo Vecchio ASAP explore congregation INRIA Saclay, Ile de France sud 4, Rue J. Monod, 91893 Orsay Cedex - FRANCE massimo.vecchio@inria.fr AbstractEnergy is a principal(a) shyness in the design and deployment of wireless detector net profits (WSNs) since sensor nodes be typically powered by batteries with a expressage capacity. 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. Keywords-Wireless sensor networks; data compression; multi-objective genetic algorithms; energy ef?ciency; portend processing; I. I NTRODUCTION A wireless sensor network (WSN) consists of a set of autonomous systems, called sensor nodes, communication among themselves and deployed in large scale (from tens to thousands) for applications such as environmental, home background and structural monitoring, disaster...If you want to get a full essay, state it on our website: OrderCustomPaper.com
