Online Calibration of Path Loss Exponent in Wireless Sensor Networks

Mao, Guoqiang; Anderson, Brian; Fidan, Baris


The path loss exponent (PLE) is a parameter indicating the rate at which the received signal strength (RSS) decreases with distance, and its value depends on the specific propagation environment. Path loss exponent estimation plays an important role in distance-based wireless sensor network localization, where distance is estimated from the RSS measurements. Path loss exponent estimation is also useful for other purposes like sensor network dimensioning. Existing techniques on PLE estimation...[Show more]
