Autonomous Vehicles Localization in Multi-Hop Mobile Underwater Wireless Networks

Autonomous Underwater Vehicles (AUV) maintain their location information during navigation in order to reach a pre-determined destination. Most of previous underwater localization approaches assume that all AUVs are within one hop, which severely restricts the scale of the AUVs. In this paper, we localize AUVs in a multihop Mobile Underwater Wireless Network (MUWN) via surfacing a 3-dominating set of AUVs as beacons. Our scheme surfaces only beacon AUVs to obtain accurate location information from external sources such as satellites, then localizes the remaining AUVs as reference. Simulation result shows that our scheme greatly improves energy efficiency, security against detection and localization accuracy.
