摘要: Localization has always been an essential application of underwater acoustic sensor networks (UASNs), which plays important role in routing strategies design, node recycling, and so on. The complex ocean condition, prior infrastructure deployment, time synchronization among beacons challenge the UASN’s localization. To solve these problems, we propose a novel localization algorithm based on virtual assistance. is classified into two parts current marine environment, including Virtual Assisted Static (VAS) Dynamic (VAD) algorithm. An auxiliary node, does not directly participate localization, deployed for setup, error measurement, RSSI ranging. GPS-equipped ship utilizes geometry to realize without complicated deployment procedures synchronization. simulation results show that our proposed can achieve properties, high coverage small as well low communication overhead UASNs.
