An impact study of the most relevant factors which influence the performance of general positioning structures in underwater sensor networks is conducted within this work. A major contribution of this work is the performance evaluation of four different positioning procedures and the influences of the water physical properties in the positioning performance achievements. Among others the authors investigate the performance dependence on temperature, salinity, and depth. The four approaches selected to perform this study are the ad-hoc positioning structure (AHPOS), the robust positioning scheme (RPS), the n-hop multilateration (N-HOP) algorithm and a new proposed approach known as the accurate underwater positioning (APOS). The performance comparison and discussion is based on the authors' simulation results. Finally the authors conclude this work with their major findings regarding the deployment of positioning systems for underwater sensor networks.
