Prior work mainly focused on the dynamics of constellation topology, routing algorithms against the topological motion, and the behavior of LEO constellation networks, but neglected real-time and completeness properties. In our work, we design a real-time and complete network simulation framework, named LEOCN, that is more meaningful and detailed for researchers than previous work on LEO satellite constellation simulations. LEOCN is supported by Linux System, which makes the framework more realistic and relieves the computational burden. Meanwhile, LEOCN deeply considers topology and routing algorithms, visualization, satellite mobility, communication protocols, and network traffic problems. On LEOCN, we can deploy routing algorithm experiments via SDN. We evaluate the performance of LEOCN in large-scale constellation scenarios, and the results demonstrate the superiority of the real-time and complete network simulation framework.<\/jats:p>","DOI":"10.3233\/jhs-222061","type":"journal-article","created":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T11:06:14Z","timestamp":1695985574000},"page":"1-18","source":"Crossref","is-referenced-by-count":1,"title":["LEOCN: Real-time and complete network simulation framework for LEO constellation networks1"],"prefix":"10.1177","volume":"30","author":[{"given":"Cong","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyang","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weipeng","family":"Liang","sequence":"additional","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunhao","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongyang","family":"Yan","sequence":"additional","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teng","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute of Artificial Intelligence, Guangzhou University, Guangzhou, Guangdong, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Li","sequence":"additional","affiliation":[{"name":"CASIC Space Engineering Development Co., Ltd, 430416 Hubei, Pepole\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianwei","family":"He","sequence":"additional","affiliation":[{"name":"CASIC Space Engineering Development Co., Ltd, 430416 Hubei, Pepole\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/JHS-222061_ref1","doi-asserted-by":"crossref","unstructured":"D.\u00a0Bhattacherjee, W.\u00a0Aqeel, I.N.\u00a0Bozkurt, A.\u00a0Aguirre and A.\u00a0Singla, Gearing up for the 21st century space race, in: The 17th ACM Workshop, 2018.","DOI":"10.1145\/3286062.3286079"},{"key":"10.3233\/JHS-222061_ref2","doi-asserted-by":"publisher","DOI":"10.1145\/3359989.3365407"},{"key":"10.3233\/JHS-222061_ref5","doi-asserted-by":"publisher","DOI":"10.1109\/INFOCOM42981.2021.9488806"},{"key":"10.3233\/JHS-222061_ref6","doi-asserted-by":"publisher","DOI":"10.1109\/INFOCOMWKSHPS51825.2021.9484491"},{"key":"10.3233\/JHS-222061_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2020.107166"},{"key":"10.3233\/JHS-222061_ref10","unstructured":"G.\u00a0Giuliari, T.\u00a0Ciussani, A.\u00a0Perrig and A.\u00a0Singla, ICARUS: Attacking low Earth orbit satellite networks, in: 2021 USENIX Annual Technical Conference (USENIX ATC 21), USENIX Association, 2021, pp.\u00a0317\u2013331, https:\/\/www.usenix.org\/conference\/atc21\/presentation\/giuliari.
