One of the main concerns in underground working tunnels is ensuring the safety of the workers and their equipment. Being aware of the real-time position of personnel in such harsh environment is challenging and requires a sophisticated localization system. With traditional Received Signal Strength (RSS) failing to accurately estimate the distance between nodes due to multipath effect in such long...
One of the main concerns in underground working tunnels is ensuring the safety of the workers and their equipment. Being aware of the real-time position of personal in such hash environments is challenging and requires a sophisticated localization system. Due to extreme multipath and non-line of sight (NLOS) conditions, wireless signals in underground narrow-vein tunnels suffer multiple kinds of distortions...
