An ATM-based multicast intersatellite routing for LEO satellite networks

摘要

Low Earth Orbit (LEO) satellite communication systems with InterSatellite Links (ISLs) are promising as a world-wide multimedia core network infrastructure. As satellites come to higher latitudes in polar orbit constellation, the degradation of ISL transmission quality becomes large because of ISL interference and relative angular velocity between satellites in adjacent orbits. This paper deals with the transmission quality of ISLs based on the general transmission model. We propose an ATM-based multicast routing approach with link weight which overcomes the degradation of transmission quality and show that this approach enhances transmission' quality significantly by computer simulation.
