Efficient Underwater RSS Value to Distance Inversion Using the Lambert Function

Abstract: There are many applications for using wireless sensor networks (WSN) in ocean science; however, identifying the exact location of a sensor by itself (localization) is still a challenging problem, where global positioning system (GPS) devices are not applicable underwater. Precise distance measurement between two sensors is a tool of localization and received signal strength (RSS), reflecting transmission loss (TL) phenomena, is widely used in terrestrial WSNs for that matter. Underwater acoustic sensor network… Show more

“…e Lambert W-function further can be evaluated only approximately through the Householder iterative procedures which also require the appropriate initial starting point. e analysis of this initial starting point has wider applicability, because the Lambert W-function has extensive use in many branches of physics and technology [55,56].…”

“…RDBF also controls the transmission time of multiple forwarders to reduce the redundancy. In [6], the authors have addressed the problems of localization by expressing underwater transmission loss via the Lambert W function. Real device implementation demonstrated the accuracy and efficiency of the proposed equation in distance calculation, computation stability, and shorter processing time.…”
