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...

An Effective Routing Algorithm for Low-earth Orbit Satellite Networks

A new routing algorithm for Low-earth orbit (LEO) satellite networks is designed in this study. For this reason genetic algorithms are used. A new objective function is obtained to find the suitable path according to the criteria of the delay and an aging factor. Also Call Blocking Probabilities (CBPs) are considered due to the dynamic nature of the satellite systems. This dynamic routing type ...

Traffic Load Balancing in Low Earth Orbit Satellite Networks

One of the unique traffic features of low earth orbit (LEO) satellite networks is time-variant and nonuniform load distribution. This feature results in a locally biased congestion problem for the LEO satellite systems. In this paper, we propose a traJjcic load balancing scheme to resolve the congestion problem in such traffic scenarios. The proposing scheme makes use of near-neighbor residual ...
