A delay between the time of fall and the time of medical attention can exacerbate injury if the fall resulted in a concussion, traumatic brain injury, or bone fracture. The authors present a solution capable of finding and tracking, in real-time, the location of an elderly person within an indoor facility, using only existing Wi-Fi infrastructure. This paper discusses the development of an open source software framework capable of finding the location of an individual within 3m accuracy using 802.11 Wi-Fi in good coverage areas. This framework is comprised of an embedded software layer, a Web Services layer, and a mobile application for monitoring the location of individuals, calculated using trilateration, with Kalman filtering employed to reduce the effect of multipath interference. The solution provides a real-time, low cost, extendible solution to the problem of indoor geolocation to mitigate potential harm to elderly persons who have fallen and require immediate medical help.<\/jats:p>","DOI":"10.4018\/ijitn.2020040101","type":"journal-article","created":{"date-parts":[[2020,1,31]],"date-time":"2020-01-31T13:46:11Z","timestamp":1580478371000},"page":"1-21","source":"Crossref","is-referenced-by-count":6,"title":["Real-Time Indoor Geolocation Tracking for Assisted Healthcare Facilities"],"prefix":"10.4018","volume":"12","author":[{"given":"Kinjal","family":"Gala","sequence":"first","affiliation":[{"name":"San Diego State University, San Diego, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul David","family":"Bryden","sequence":"additional","affiliation":[{"name":"University of Strathclyde, Glasgow, Scotland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6563-917X","authenticated-orcid":true,"given":"Christopher","family":"Paolini","sequence":"additional","affiliation":[{"name":"San Diego State University, San Diego, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Wang","sequence":"additional","affiliation":[{"name":"University of California, Los AngelesUSA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albena Dimitrova","family":"Mihovska","sequence":"additional","affiliation":[{"name":"CTIF Global Capsule (CGC), Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahasweta","family":"Sarkar","sequence":"additional","affiliation":[{"name":"San Diego State University, San Diego, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJITN.2020040101-0","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/254345"},{"key":"IJITN.2020040101-1","unstructured":"BeagleBoard.org Foundation.
