However, a major drawback of energy harvesting is its varying and intermittent characteristic, which can negatively affect the quality of service. This calls for careful design and operation of the nodes, possibly by means of, e.g., dynamic duty cycling and\/or dynamic frequency and voltage scaling. In this context, various energy prediction models have been proposed in the literature; however, they are typically compute-intensive or only suitable for a single type of energy source. In this paper, we propose Linear Energy Prediction \u201cLINE-P\u201d, a lightweight, yet relatively accurate model based on approximation and sampling theory; LINE-P is suitable for dual-source energy harvesting. Simulations and comparisons against existing similar models have been conducted with low and medium resolutions (i.e., 60 and 22 min intervals\/24 h) for the solar energy source (low variations) and with high resolutions (15 min intervals\/24 h) for the wind energy source. The results show that the accuracy of the solar-based and wind-based predictions is up to approximately 98% and 96%, respectively, while requiring a lower complexity and memory than the other models. For the cases where LINE-P\u2019s accuracy is lower than that of other approaches, it still has the advantage of lower computing requirements, making it more suitable for embedded implementation, e.g., in wireless sensor network coordinator nodes or gateways.<\/jats:p>","DOI":"10.3390\/s17071666","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T11:21:59Z","timestamp":1500549719000},"page":"1666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Dual-Source Linear Energy Prediction (LINE-P) Model in the Context of WSNs"],"prefix":"10.3390","volume":"17","author":[{"given":"Faisal","family":"Ahmed","sequence":"first","affiliation":[{"name":"Thomas Johann Seebeck Department of Electronic, Tallinn University of Technology, Tallinn 12616, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1460-6612","authenticated-orcid":false,"given":"Gert","family":"Tamberg","sequence":"additional","affiliation":[{"name":"Department of Cybernetics, Tallinn University of Technology, Tallinn 12616, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4667-621X","authenticated-orcid":false,"given":"Yannick","family":"Le Moullec","sequence":"additional","affiliation":[{"name":"Thomas Johann Seebeck Department of Electronic, Tallinn University of Technology, Tallinn 12616, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4902-1289","authenticated-orcid":false,"given":"Paul","family":"Annus","sequence":"additional","affiliation":[{"name":"Thomas Johann Seebeck Department of Electronic, Tallinn University of Technology, Tallinn 12616, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,7,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wu, F., R\u00fcdiger, C., and Yuce, M.R.
