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.

Satellite constellations for a multiple LEO satellite network

Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1993
AbstractRecently, research has been very active in communication networks that could service the entire globe by using multiple, low, earth‐orbiting satellites. This has been spurred on by progress in the field of digital communication technique, technical advances of satellite launching, and a decrease in the costs of small‐sized satellites.In this ...

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 ...

Routing in LEO-based satellite networks

1999 IEEE Emerging Technologies Symposium. Wireless Communications and Systems (IEEE Cat. No.99EX297), 2003
Several strategies have been proposed for routing in a low Earth orbit (LEO) satellite system. Some of them are based on the Internet protocol (IP) and a few on asynchronous transfer mode (ATM) switching. However, issues like memory requirements of the satellites in the LEO network and the overheads involved in transmitting packets over the network ...

Multipath TCP over LEO satellite networks

2015 International Wireless Communications and Mobile Computing Conference (IWCMC), 2015
Low earth orbit (LEO) satellite networks like Iridium have played a pivotal role in providing ubiquitous network access services to areas without terrestrial infrastructure because of their potential for global coverage and high bandwidth availability. With low orbit and short range as compared to geostationary satellites, LEO satellites are accessible

Network management in ATM LEO satellite networks

Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003
Development of the past decade have confirmed that ATM technology has the potential of becoming the transport mechanism in many multimedia networks where high-speed traffic and Quality of Service guarantees must be provided. More recently, we have witnessed a surge of interest in Low Earth Orbiting (LEO) satellite networks with on-board ATM switches ...

Adaptive routing in LEO satellite networks

VTC2000-Spring. 2000 IEEE 51st Vehicular Technology Conference Proceedings (Cat. No.00CH37026), 2002
One of the unique traffic features of low earth orbit (LEO) satellite networks is nonuniform traffic load distribution. Moreover, the traffic distribution is time-variant since each individual satellite moves along its orbit plane and the earth rotates on its axis simultaneously.

Resource management in LEO satellite networks

IEEE Potentials, 2003
To provide truly global coverage needed by increased Personal Communication Services (PCS), a new generation of mobile satellite networks has been proposed. These low Earth orbit (LEO) mobile satellite networks handle multimedia traffic and can be used for non-real-time as well as real-time service to remote areas.
