Omnidirectional free-space optical (FSO) receivers
SPIE Proceedings, 2007Free-space optics (FSO) is a technology that utilizes modulated light beam to transmit information through the atmosphere. Line-of-sight connection between both FSO transceivers is a necessary condition to maintain continuous exchange of voice, video, and data information. To date, the primary concentration of mobile FSO research and development has

Protocol Design for Free Space Optical (FSO) Communication
Applied Mechanics and Materials, 2015A new transceiving protocol is designed for an FSO communication system, and it’s discussed from the transmitting protocol and the receiving protocol. Different from wired communication, a FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere, and the protocol is optimized for terrestrial FSO ...

Basic concept of free space optics communication (FSO): An overview
2015 International Conference on Communications and Signal Processing (ICCSP), 2015Now a days the wireless technology has become popular in the wireless system. FSO is a technology that uses the visible to near infrared (NIR) light propagating through the atmosphere to transmit information. FSO communications are attracting attention as the contemporary engineering science to resolve the last mile bottleneck issues in local area ...

Free Space Optical Communications (FSO)
2007 IEEE Avionics, Fiber-Optics and Photonics Technology Conference, 2007Free space optical communications (FSO) is now common for point to point communications between fixed locations on land, and is also used for communication between moving platforms on land, on the surface of the sea, in air, and in space. Free space implies that it is not practical to use optical fiber to connect the points that need to communicate or ...

Proceedings of the 4th ACM Workshop on Wearable Systems and Applications, 2018
In near future, we expect the Virtual Reality (VR) headsets to be wireless and to be demanding data-rate up to Tbps, thus pushing RF technology to the limit. In this work, we explore the possibility of using steerable Free Space Optics (FSO) to create a wireless link between a wall-mounted static transceiver and a VR headset in motion with its user. We

A Throughput Model of TCP-FSO/ADFR for Free-Space Optical Satellite Communications
2019 IEEE Global Communications Conference (GLOBECOM), 2019We developed an analytic characterization of the steady-state throughput of a free-space optical satellite communications (FSOSC) system which includes an ultra-high-speed transmission control protocol for FSOSC (TCP-FSO) and an adaptive- distributed-frame-repetition (ADFR) technique.

A battery recharge model for WSNs using Free-Space Optics (FSO)
2008 IEEE International Multitopic Conference, 2008One of the most critical limiting factor for a Wireless Sensor Network (WSN) is its battery life. Therefore, a very desirable feature of WSN would be its rechargability to remain operational over longer period of times. However, the nodes needing recharge may not be accessible. In this paper, we present a battery recharge model in WSNs for inaccessible
