Abstract:
Electromagnetic (EM) radios have been recently proposed for underwater sensor networks. Due to the short transmission range of EM radio transmissions underwater, new localization techniques are required for underwater sensor networks using these radios. We propose and evaluate three localization approaches for EM-based underwater sensor networks: (1) multilateration with the aid of autonomous underwater vehicles (AUVs), (2) multi-dimensional scaling (MDS) without the AUVs, and (3) a hybrid approach combining MDS and multilateration. We compare performance of the three approaches with simulations. The main disadvantage of AUV-aided localization with multilateration is that it does not always provide complete localization coverage of the network. On the other hand, MDS provides complete localization coverage, but its performance decreases in sparse networks. The hybrid approach provides complete network coverage and improves the performance of MDS in sparse networks.
