Network Slicing in LEO Satellite Network

2021 2nd International Conference on Artificial Intelligence and Information Systems, 2021
To solve the problems of LEO (Low Earth Orbit) satellite network, such as insufficient flexibility and low resource utilization, an architecture using network slicing technology is proposed. Then a prototype system based on the Docker platform and DTN (Delay Tolerant Network) is implemented, providing IMS (IP Multimedia Subsystem) network slice ...

Networking in LEO Satellite

21st International Communications Satellite Systems Conference and Exhibit, 2003
The usage of LEO Satellite for multi mission application such as voice, data transmission, E-mail and remote sensing has been increasing very rapidly in recent years. This is because of its low production cost, low lunching cost and low power transmission due its low orbit.

A Network-Flows-Based Satellite Handover Strategy for LEO Satellite Networks

IEEE Wireless Communications Letters, 2021
This paper proposes a satellite handover strategy for the huge low earth orbit (LEO) satellite constellation. As the increasing of the constellation scale and the number of user terminals (UTs), the satellite handover becomes more complicated. Thus, we formulate the network-flows model of the satellite handover, and the handover UTs can access the ...

Handover strategy for LEO satellite communication using graph neural network

ICT Express
Distributed handover (HO) strategy with low complexity can provide seamless communication in low earth orbit (LEO) satellite networks. However, it is difficult to consider load balancing in distributed HO strategy, which may results in HO failures.

On the Use of LEO Satellite Constellation for Active Network Management in Power Distribution Networks

IEEE Transactions on Smart Grid, 2012
The passive nature of power distribution networks has been changing to an active one in recent years as the number of small-scale Distributed Generators (DGs) connected to them rises.

QoS Routing for LEO Satellite Networks

2013
Since the population distribution on the earth surface is highly non-uniform, the traffic requirements are unbalanced in LEO (Low Earth Orbit) satellite networks, some ISLs(Inter-Satellite Link) of satellite networks are congested while others are underutilized.
