Instead of attempting to devise novel ad hoc algorithms, we show that, given general knowledge of the parameters that must be monitored, it is possible to efficiently employ conventional Huffman coding to represent the same parameter when measured at different locations and time periods. When the data collected by the sensor nodes consists of integer measurements, the Huffman dictionary computed using statistics inferred from public datasets often approaches the entropy of the data. Results using temperature and relative humidity measurements show that even when the proposed method does not approach the theoretical limit, it outperforms popular compression mechanisms designed specifically for wireless sensor networks. <\/jats:p>","DOI":"10.1155\/2014\/672921","type":"journal-article","created":{"date-parts":[[2014,1,23]],"date-time":"2014-01-23T22:40:57Z","timestamp":1390516857000},"page":"672921","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":23,"title":["Lightweight Data Compression in Wireless Sensor Networks Using Huffman Coding"],"prefix":"10.1177","volume":"10","author":[{"given":"Henry Ponti","family":"Medeiros","sequence":"first","affiliation":[{"name":"Purdue University, 465 Northwestern Avenue, West Lafayette, IN 47907-2035, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcos Costa","family":"Maciel","sequence":"additional","affiliation":[{"name":"Federal Institute of Education, Science and Technology of Amazonas (IFAM), Campus Manaus Industrial District, Avenida Danilo Areosa, 1672, 69075-351 Manaus, AM, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7389-6245","authenticated-orcid":false,"given":"Richard","family":"Demo Souza","sequence":"additional","affiliation":[{"name":"Federal University of Technology-Paran\u00e1 (UTFPR), Avenida Sete de Setembro, 3165, 80230-901 Curitiba, PR, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo Eduardo","family":"Pellenz","sequence":"additional","affiliation":[{"name":"Pontifical Catholic University-Paran\u00e1 (PUC-PR), R.
