Differentiating itself from the existing literature, the performance of the direct link and dual-hop energy harvesting relay-aided links is analyzed under the condition of indoor fading modeled by log-normal distribution. Moreover, the manuscript presents the analytical expressions of the successful transmission probability of the deployed opportunistic decode-and-forward and amplify-and-forward relay selection scheme, and validates them with Monte Carlo simulations. Moreover, the impact of different system parameters on the successful transmission probability is revealed. For the considered hybrid system, in general, the opportunistic decode-and-forward relaying scheme outperforms the opportunistic amplify-and-forward relaying scheme. As importantly, increasing the source to relay distance and power splitting ratio over certain limits significantly deteriorates the system performance, indicated by the decrease in the successful transmission probability.<\/jats:p>","DOI":"10.3390\/s21165469","type":"journal-article","created":{"date-parts":[[2021,8,13]],"date-time":"2021-08-13T09:22:38Z","timestamp":1628846558000},"page":"5469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Opportunistic DF-AF Selection Relaying in Hybrid Wireless and Power Line Communication for Indoor IoT Networks"],"prefix":"10.3390","volume":"21","author":[{"given":"Hoang Thien","family":"Van","sequence":"first","affiliation":[{"name":"The Saigon International University (SIU), Ho Chi Minh City 700000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quyet-Nguyen","family":"Van","sequence":"additional","affiliation":[{"name":"Faculty of Technology, Dong Nai Technology University, Dong Nai 760000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danh Hong","family":"Le","sequence":"additional","affiliation":[{"name":"Van Hien University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoang-Phuong","family":"Van","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Technology, Thu Dau Mot University, Binh Duong 750000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0838-4024","authenticated-orcid":false,"given":"Jakub","family":"Jalowiczor","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, VSB\u2014Technical University of Ostrava, 17, Listopadu 2172\/15, 708 00 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1547-8416","authenticated-orcid":false,"given":"Hoang-Sy","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Robotics and Artificial Intelligence, Binh Duong University, Binh Duong 750000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5135-7980","authenticated-orcid":false,"given":"Miroslav","family":"Voznak","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, VSB\u2014Technical University of Ostrava, 17, Listopadu 2172\/15, 708 00 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1065","DOI":"10.1109\/JSAC.2014.2328098","article-title":"What will 5G be?","volume":"32","author":"Andrews","year":"2014","journal-title":"IEEE J.
