On-Demand Routing in LEO Mega-Constellations with Dynamic Laser Inter-Satellite Links
Dhiraj Bhattacharjee, Pablo G. Madoery, Aizaz U. Chaudhry +5
Low Earth orbit (LEO) satellite mega constellations are beginning to include laser inter-satellite links (LISLs) to extend the Internet to the most remote locations on Earth. Since…
Latency versus Transmission Power Trade-off in Free-Space Optical (FSO) Satellite Networks with Multiple Inter-Continental Connections
Jintao Liang, Aizaz Chaudhry, John Chinneck +5
In free-space optical satellite networks (FSOSNs), satellites connected via laser inter-satellite links (LISLs), latency is a critical factor, especially for long-distance inter-co…
Free-Space Optical (FSO) Satellite Networks Performance Analysis: Transmission Power, Latency, and Outage Probability
Jintao Liang, Aizaz U. Chaudhry, Eylem Erdogan +5
In free-space optical satellite networks (FSOSNs), satellites can have different laser inter-satellite link (LISL) ranges for connectivity. Greater LISL ranges can reduce network l…
Laser Inter-Satellite Link Setup Delay: Quantification, Impact, and Tolerable Value
Dhiraj Bhattacharjee, Aizaz U. Chaudhry, Halim Yanikomeroglu +2
Dynamic laser inter-satellite links (LISLs) provide the flexibility of connecting a pair of satellites as required (dynamically) while static LISLs need to be active continuously b…
Future Space Networks: Toward the Next Giant Leap for Humankind
Mohammed Y. Abdelsadek, Aizaz U. Chaudhry, Tasneem Darwish +5
Due to the unprecedented advances in satellite fabrication and deployment, innovative communications and networking technologies, ambitious space projects and programs, and the res…
Temporary Laser Inter-Satellite Links in Free-Space Optical Satellite Networks
Aizaz U. Chaudhry, Halim Yanikomeroglu
Laser inter-satellite links (LISLs) between satellites in a free-space optical satellite network (FSOSN) can be divided into two classes: permanent LISLs (PLs) and temporary LISLs…
On Crossover Distance for Optical Wireless Satellite Networks and Optical Fiber Terrestrial Networks
Aizaz U. Chaudhry, Halim Yanikomeroglu
Optical wireless satellite networks (OWSNs) can provide lower latency data communications compared to optical fiber terrestrial networks (OFTNs). The crossover function enables to…
Link Budget Analysis for Free-Space Optical Satellite Networks
Jintao Liang, Aizaz U. Chaudhry, Eylem Erdogan +1
Free-space optical satellite networks (FSOSNs) will employ free-space optical links between satellites and between satellites and ground stations, and the link budget for optical i…
The Digital Divide in Canada and the Role of LEO Satellites in Bridging the Gap
Tuheen Ahmmed, Afsoon Alidadi, Zichao Zhang +2
Overcoming the digital divide in rural and remote areas has always been a big challenge for Canada with its huge geographical area. In 2016, the Canadian Radio-television and Telec…
When to Crossover from Earth to Space for Lower Latency Data Communications?
Aizaz U. Chaudhry, Halim Yanikomeroglu
For data communications over long distances, optical wireless satellite networks (OWSNs) can offer lower latency than optical fiber terrestrial networks (OFTNs). However, when is i…
Phasing Parameter Analysis for Satellite Collision Avoidance in Starlink and Kuiper Constellations
Jintao Liang, Aizaz U. Chaudhry, Halim Yanikomeroglu
The phasing parameter F determines the relative phasing between satellites in different orbital planes and thereby affects the relative position of the satellites in a constellatio…
Optical Wireless Satellite Networks versus Optical Fiber Terrestrial Networks: The Latency Perspective
Aizaz U. Chaudhry, Halim Yanikomeroglu
Formed by using laser inter-satellite links (LISLs) among satellites in upcoming low Earth orbit and very low Earth orbit satellite constellations, optical wireless satellite netwo…
Laser Inter-Satellite Links in a Starlink Constellation
Aizaz U. Chaudhry, Halim Yanikomeroglu
Laser inter-satellite links (LISLs) are envisioned between satellites in upcoming satellite constellations, such as Phase I of SpaceX's Starlink. Within a constellation, satellites…
