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…
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…
On the Performance of UAV Relaying with Reconfigurable Antenna and Media Based Modulation in the Presence of Shadowed Fading
Ayse Betul Buyuksar, Eylem Erdogan, Ibrahim Altunbas
Unmanned aerial vehicles (UAVs) have attracted significant interest from the academia and industry most recently. Motivated by the wide usage of UAVs, this paper considers UAV comm…
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…
Cooperation in Space: HAPS-Aided Optical Inter-Satellite Connectivity with Opportunistic Scheduling
Eylem Erdogan, Ibrahim Altunbas, Gunes Karabulut Kurt +1
Issues with tracking, precision pointing, and Doppler shift are the major sources of performance loss in laser inter-satellite communication that can severely decrease the coverage…
Optical Satellite Eavesdropping
