According to the periodicity of the large-scale satellite network and the prior knowledge provided by acknowledgment packages, a dynamic domain-based adaptive access algorithm (DAA) is proposed in this paper. Firstly, this algorithm divides the large-scale satellite network into different domains according to the minimum elevation angle of the Earth station (ES) and the predictable characteristics of the trajectory of the satellite. Then, the ES selects the access satellites according to the relationship between the traffic volume and the satellites\u2019 coverage time. Finally, the ES selects the backup access satellite based on the satellites\u2019 coverage time, the traffic volume of the ES, satellite status provided by prior knowledge, and other information. When the access satellite cannot satisfy the communication demand, the ES adaptively switches the earth-satellite link to the backup access satellite. The ES first choice of access satellite does not require interaction with the satellites, reducing the consumption of communication resources. The selection strategy of backup access satellite and the concept of virtual destination address proposed in this paper can reduce the routing overhead after switching. Through theoretical analysis and simulation results in the StarLink constellation, it is proved that this paper improves the coverage time utilization of accessing satellites and reduces the switching probability compared with the traditional access algorithm, which is more suitable for ES to access large-scale satellite networks.<\/jats:p>","DOI":"10.3390\/s22165995","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T23:05:49Z","timestamp":1660259149000},"page":"5995","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Adaptive Access Selection Algorithm for Large-Scale Satellite Networks Based on Dynamic Domain"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7687-0852","authenticated-orcid":false,"given":"Gaosai","family":"Liu","sequence":"first","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinglong","family":"Jiang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Shanghai Engineering Center for Microsatellites, Shanghai 201204, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huawang","family":"Li","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Shanghai Engineering Center for Microsatellites, Shanghai 201204, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenhua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyue","family":"Sun","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Shanghai Engineering Center for Microsatellites, Shanghai 201204, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guang","family":"Liang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201204, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Shanghai Engineering Center for Microsatellites, Shanghai 201204, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1016\/j.actaastro.2019.03.040","article-title":"A technical comparison of three low earth orbit satellite constellation systems to provide global broadband","volume":"159","author":"Cameron","year":"2019","journal-title":"Acta Astronaut."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1109\/MWC.2017.1700043","article-title":"Radio Resource Management in Future Terrestrial-Satellite Communication Networks","volume":"24","author":"Kuang","year":"2017","journal-title":"IEEE Wirel.
