Analyzing the performance of localization algorithms in underwater sensor networks

Under the background of the Age of Big Ocean, much emphasis have been paid on the marine development and utilization of the ocean. So the Underwater Wireless Networks (UWSNs) have been attracted much attention in the industrial community and the academic community. In this paper, we compare the performance of three localization algorithms: the DV-Hop, the 3D-RPE and the LSL which are suitable for many applications in the large scale UWSNs. The simulation results indicate that the average error and the average energy consumption of the DV-Hop are greater than those of the 3D-RPE and the LSL. In addition, the localization rate of the DV-Hop is affected by the trust value easily and only when the trust value is quite low, the localization rate can meet the requirement. In the same situation, the localization rate and the energy consumption of the 3D-RPE and the LSL are quite similar, while the average error of the LSL is smaller than that of the 3D-RPE.
