This paper discusses the implementation and evaluation of the two-hop real-time LoRa (Two-hop RT-LoRa) protocol previously proposed to be used for industrial monitoring and control applications. The protocol was implemented on LoRa devices to support a multi-hop LoRa network that consists of one LoRa gateway and 40 end devices. It is shown with various campus deployment scenarios that the protocol improves reliability in data transmission significantly<\/jats:p>","DOI":"10.12720\/jcm.17.4.273-279","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T06:41:03Z","timestamp":1652424063000},"page":"273-279","source":"Crossref","is-referenced-by-count":7,"title":["Implementation and Evaluation of Multi-hop LoRa Networks"],"prefix":"10.12720","author":[{"name":"Department of Electrical, Electronic and Computer Engineering, University of Ulsan, Ulsan 680-749, South Korea","sequence":"first","affiliation":[]},{"given":"Huu Phi","family":"Tran","sequence":"first","affiliation":[]},{"given":"Hoon","family":"Oh","sequence":"additional","affiliation":[]}],"member":"4977","published-online":{"date-parts":[[2022]]},"container-title":["Journal of Communications"],"original-title":[],"link":[{"URL":"http:\/\/www.jocm.us\/uploadfile\/2022\/0329\/20220329074722823.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T06:41:28Z","timestamp":1652424088000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.jocm.us\/show-268-1755-1.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022]]},"references-count":0,"URL":"https:\/\/doi.org\/10.12720\/jcm.17.4.273-279","relation":{},"ISSN":["2374-4367"],"issn-type":[{"type":"print","value":"2374-4367"}],"subject":[],"published":{"date-parts":[[2022]]}}}
