This study proposes the Smart Sensor Node Group Management Medium Access Control Scheme designed to group smart sensor devices and collect data from them efficiently. The proposed scheme performs grouping of portable sensor devices connected to a system depending on the distance from the sink node and transmits data by setting different buffer thresholds to each group. This method reduces energy consumption of sensor devices located near the sink node and enhances the IoT system\u2019s general energy efficiency. When a sensor device is moved and, thus, becomes unable to transmit data, it is allocated to a new group so that it can continue transmitting data to the sink node.<\/jats:p>","DOI":"10.3390\/informatics5010015","type":"journal-article","created":{"date-parts":[[2018,3,20]],"date-time":"2018-03-20T06:57:11Z","timestamp":1521529031000},"page":"15","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Smart Sensor Data Transmission Technique for Logistics and Intelligent Transportation Systems"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3732-7328","authenticated-orcid":false,"given":"Kyunghee","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Kyung Hee University, 1732, Deogyeong-daero, Giheung-gu, Yongin-si 17104, Gyeonggi-do, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6630-1189","authenticated-orcid":false,"given":"Intae","family":"Ryoo","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Kyung Hee University, 1732, Deogyeong-daero, Giheung-gu, Yongin-si 17104, Gyeonggi-do, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Taniguchi, E., Thompson, R.G., and Yamada, T.
