The characteristics of multi-coverage of multilayer satellite networks make sure of good validity and reliability of the space-based networks. Walker delta type constellation guarantees permanent inter satellite links between satellites in the same layer and provides nonpermanent inter orbit links, both of which make an autonomic satellite backbone. As a integrated services network, multiplayer satellite...
Polar and quasi-polar orbit constellations have "seams" between counter-rotated orbits, and ISLs need switch off above the polar regions. Satellite communication networks made up of Walker constellations have steady topology and good ISL performance. Adaptive routing strategy uses path-weight instead of delay or delay jitter as a criterion to select a path under three service models. Numerical...
