OCC-ID: New Broadcasting Service-Based Cloud Model and Image Sensor Communications
International Journal of Distributed Sensor Networks, 2016 In recent decades, the main data traffic of mobile communication is based on the RF technology. Even though the efficiency from optimization for utilization or reuse is applied, there is a limitation of increased traffic demand of RF communication ...

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
, 2007 The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence

Investigating the angular distortion impact on vehicular optical camera communication (OCC) systems
Optics ExpressOptical camera communication (OCC) shows promise for optical wireless communication (OWC) in vehicular networks. However, vehicle mobility-induced angular distortions hinder system throughput by degrading non-isotropic vehicular OCC channel gain. Few of the prior works have ever made a comprehensive analysis of their impact, especially based on the ...
