Optimization of the problem of Handover in the constellations of satellites in low orbit

INTERLINK: A Digital Twin-Assisted Storage Strategy for Satellite-Terrestrial Networks

“…The weights of the graph are assigned regarding various handover standards. El Houda Hedjazi et al [22] evaluated several LEO satellite constellation channel allocation strategies and simulated the impact of handover on the probability of call blocking. A satellite handover strategy based on the potential game of mobile terminals in the LEO network is presented [23].…”

Selection of handoff method for serving air traffıc control communication in Leo satellite constellation

“…Few studies have been carried out on the issue of satellite handover, investigating channel allocation policies for new and handover contacts using mainly fixed channel allocation (FCA) techniques. In this paper different queuing policies for handover requests were investigated in order to enhance them in air navigation satellite communication [9]. This paper is organized as follows: Section 2 presents the data model and lists the assumptions and some preliminary notions.…”
