While highly-dense wireless networks provide efficient and sustainable solutions to collect precise environmental information, a new channel access scheme is needed to solve the channel collision problem caused by the large number of competing nodes accessing the channel simultaneously. In this paper, we propose a space-time random access method based on a directional data transmission strategy, by which collisions in the wireless channel are significantly decreased and channel utility efficiency is greatly enhanced. Simulation results show that our proposed method can decrease the packet loss rate to less than     2 %     in large scale WSNs and in comparison with other channel access schemes for WSNs, the average network throughput can be doubled.<\/jats:p>","DOI":"10.3390\/s16071108","type":"journal-article","created":{"date-parts":[[2016,7,18]],"date-time":"2016-07-18T09:38:03Z","timestamp":1468834683000},"page":"1108","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Low Collision and High Throughput Data Collection Mechanism for Large-Scale Super Dense Wireless Sensor Networks"],"prefix":"10.3390","volume":"16","author":[{"given":"Chunyang","family":"Lei","sequence":"first","affiliation":[{"name":"School of Information and Communication Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongxia","family":"Bie","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gengfa","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Computing and Communications, University of Technology Sydney, Sydney 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2943-2037","authenticated-orcid":false,"given":"Elena","family":"Gaura","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Computing, Coventry University, Coventry CV1 5FB, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Brusey","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Computing, Coventry University, Coventry CV1 5FB, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuekun","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eryk","family":"Dutkiewicz","sequence":"additional","affiliation":[{"name":"School of Computing and Communications, University of Technology Sydney, Sydney 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lei, C., Bie, H., Fang, G., Mueck, M., and Zhang, X.
