These networks are characterized by long propagation delays, error-prone channels and half-duplex communication. In this paper, we address the problem of energy-efficient communication through the use of optimized channel coding parameters. We consider a two-layer encoding scheme employing forward error correction (FEC) codes and fountain codes (FC) for UAN scenarios without feedback channels. We model and evaluate the energy consumption of different channel coding schemes for a K-distributed multipath channel. The parameters of the FEC encoding layer are optimized by selecting the optimal error correction capability and the code block size. The results show the best parameter choice as a function of the link distance and received signal-to-noise ratio.<\/jats:p>","DOI":"10.3390\/s17040728","type":"journal-article","created":{"date-parts":[[2017,3,31]],"date-time":"2017-03-31T10:35:49Z","timestamp":1490956549000},"page":"728","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Energy-Efficient Channel Coding Strategy for Underwater Acoustic Networks"],"prefix":"10.3390","volume":"17","author":[{"given":"Grasielli","family":"Barreto","sequence":"first","affiliation":[{"name":"Postgraduate Program in Computer Science (PPGIa), Pontifical Catholic University of Parana, Paran\u00e1 80215-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Sim\u00e3o","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology, Paran\u00e1 80230-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6108-6272","authenticated-orcid":false,"given":"Marcelo","family":"Pellenz","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Computer Science (PPGIa), Pontifical Catholic University of Parana, Paran\u00e1 80215-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7389-6245","authenticated-orcid":false,"given":"Richard","family":"Souza","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Santa Catarina, Santa Catarina 88040-900, Florian\u00f3polis, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edgard","family":"Jamhour","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Computer Science (PPGIa), Pontifical Catholic University of Parana, Paran\u00e1 80215-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manoel","family":"Penna","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Computer Science (PPGIa), Pontifical Catholic University of Parana, Paran\u00e1 80215-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glauber","family":"Brante","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology, Paran\u00e1 80230-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Chang","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology, Paran\u00e1 80230-901, Curitiba, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, N., Martinez, J.F., Meneses Chaus, J.M., and Eckert, M.
