Abstract :
Underwater sensor network can achieve the unmanned environmental monitoring and military monitoring missions. Underwater acoustic sensor node cannot rely on the GPS to position itself, and the traditional indirect positioning methods used in Ad Hoc networks are not fully applicable to the localization of underwater acoustic sensor networks. In this paper, we introduce an improved underwater acoustic network localization algorithm. The algorithm processes the raw data before localization calculation to enhance the tolerance of random noise. We reduce the redundancy of the calculation results by using a more accurate basic algorithm and an adjusted calculation strategy. The improved algorithm is more suitable for the underwater acoustic sensor network positioning.
