It is well known that the effect of shadowing on a visible light communication (VLC) system is severe due to its line of sight propagation nature. Hence, shadowing can seriously impair the system performance. In this paper, we propose a method to take advantage of the optical diffraction phenomenon to overcome shadowing by employing a receiver with a wide field-of-view (FOV). We have modelled the...
The propagation characteristics of electromagnetic waves in underground mines are different from those in free space because of the harsh underground environment. Physical phenomena like severe reflection, scattering, and diffraction along the mines’ rough walls will affect the propagation of electromagnetic waves. Channel predictions are crucial for reliable and optimal wireless communication in...
A series of unfortunate worldwide mine disasters took place recently and shock the world, the disasters ranged from collapsed mines causing death to trapping miners underground which caused many life losses and injuries. The importance of robust and reliable underground communication networks has become evident once again. A reliable underground communication network in mines will not only facilitate...
After a series of recent world wide mine tragedies, ranging from collapsing mines in China and Colombia to trapped miners in Chile, the importance of robust and reliable underground communication networks has become evident once again. A reliable underground communication network in mines will not only facilitate the day to day operations but will also help save many lives. However, designing reliable...
