In this article, we introduce\n            <jats:italic>CoSA<\/jats:italic>\n            , a link-aware real-time video streaming system for mobile devices. The proposed system utilizes a 3D camera to distinguish the region of importance (ROI) and non-ROI region within the video frame. Based on the link-state feedback from the receiver, the proposed system allocates a higher bandwidth for the region that is classified as ROI and a lower bandwidth for non-ROI in the video stream by reducing the video's bit rate. We implemented\n            <jats:italic>CoSA<\/jats:italic>\n            in a real test-bed where the IEEE 802.11 is employed as a medium for wireless networking. Furthermore, we verified the effectiveness of the proposed system by conducting a thorough empirical study. The results indicate that the proposed system enables real-time video streaming while maintaining a consistent visual quality by dynamically reconfiguring video coding parameters according to the link quality.\n          <\/jats:p>","DOI":"10.1145\/2771438","type":"journal-article","created":{"date-parts":[[2015,8,26]],"date-time":"2015-08-26T14:00:30Z","timestamp":1440597630000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Link-Aware Reconfigurable Point-to-Point Video Streaming for Mobile Devices"],"prefix":"10.1145","volume":"12","author":[{"given":"Suk Kyu","family":"Lee","sequence":"first","affiliation":[{"name":"Korea University, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seungho","family":"Yoo","sequence":"additional","affiliation":[{"name":"Korea University, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jongtack","family":"Jung","sequence":"additional","affiliation":[{"name":"Korea University, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hwangnam","family":"Kim","sequence":"additional","affiliation":[{"name":"Korea University, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jihoon","family":"Ryoo","sequence":"additional","affiliation":[{"name":"Stony Brook University, Stony Brook, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2015,8,24]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/T-C.1974.223784"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1943552.1943574"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2010.08.006"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/TNSM.2009.090602"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2011.072611.100066"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TCOM.1979.1094560"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2012.07.024"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2005.845636"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/1870121.1870126"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2010.08.010"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1049\/el:20080522"},{"key":"e_1_2_1_13_1","unstructured":"ITU-T Recommendation J.247. 2008.
