Abstract


The main aim of this article is to provide the information about vulnerability of wireless sensors networks to weather-based disruptions. Article is based on different expert’s opinions, published in a lot of scientific materials. All the useful references are given in references section. Introduction gives a short information about wireless signals in real world conditions – it is described how weather affects signals (rain, fog and clouds, snow, hail, lightning, wind, bodies of water, trees and physical obstruction). Information about the effects of weather on wireless sensor networks using Free Space Optical / Radio Frequency (FSO/RF) communication are then provided. Finally, the impact of weather conditions on MANET routing protocols are presented in theoretical manner, and experimental simulations are performed by comparing different protocols sustainability to different weather conditions. After investigation of experiment results, ideas about how to decrease a vulnerability of wireless networks to weather-based disruptions are discussed.
