| Abstract: | The access strategy is studied for multi-layered satellite networks, which includes node addressing, user location registering and updating, and selecting methods for multi-satellites. By comparing several selecting methods for multi-satellites commonly used in single-layered satellite networks, the selecting methods for multi-satellites in multi-layered satellite networks are put forward. Further- more, the access strategy proposed was analyzed through simulation of a layered satellite network to come to a conclusion that the pro- posed access strategy is fit for multi-layered satellite networks. |
