Handover Management in Low Earth Orbit (LEO) Satellite Networks
Low Earth Orbit (LEO) satellite networks will play an important role in the evolving information infrastructure. Satellites in the low earth orbits provide communication with shorter end-to-end delays and efficient frequency usage. However, some problems need to be solved before LEO satellite systems can be successfully deployed. One of these problems is the handover management. The objective o...
متن کاملStaged Deployment of Communications Satellite Constellations in Low Earth Orbit
The “traditional” way of designing constellations of communications satellites in low Earth orbit is to optimize the design for a specified global capacity. This approach is based on a forecast of the expected number of users and their activity level, both of which are highly uncertain. This can lead to economic failure if the actual demand is significantly smaller than the one predicted. This ...
متن کاملAnalysing the Orbital Movement and Trajectory of LEO (Low Earth Orbit) Satellite Relative to Earth Rotation
Next generation of wireless Internet scenarios include LEOs (Low Earth Orbit Satellites). Lower altitudes of LEO constellations could allow global coverage while offering: low end-to-end propagation delay, low power consumption, and effective frequency usage both for the users and the satellite network. LEOs rotate asynchronously to the earth rotation. Fast movement of LEOs makes it necessary t...
متن کاملA routing algorithm for connection-oriented Low Earth Orbit (LEO) satellite networks with dynamic connectivity
Low Earth Orbit (LEO) satellites move with respect to a fixed observer on the Earth surface. Satellites in the polar regions and the seam switch off their intersatellite links to the neighbor satellites. As a result, the connectivity pattern of the network changes. Ongoing calls passing through these links need to be rerouted. A large number of simultaneous rerouting attempts would cause excess...
متن کاملCall Admissibility for Multiservice Traffics in Low-Earth Orbit (LEO) Satellite Networks*
In a LEO system, a user’s call may be handed over constantly from one satellite to another due to visibility changes caused by satellites’ movements. The resultant system performance will degrade if handover calls occur frequently but few are transferred successfully. This paper considered a multiservice LEO system that allows different bandwidth/channel allocations (so-called multirate) on-dem...
