A Communication Framework for Networked Autonomous Underwater Vehicles

摘要: Underwater acoustic communications consume a significant amount of energy due to the high transmission power (10–50 \(\mathrm {W}\)) and long data packet duration (0.1–1 {s}\)). Mobile Autonomous Vehicles (AUVs) can conserve by waiting for ‘best’ network topology configuration, e.g., favorable alignment, before starting communicate. Due frequency-selective underwater ambient noise medium absorption—which increases exponentially with distance—a shorter distance between AUVs translates into lower loss higher available bandwidth. By leveraging predictability AUV trajectories, novel solution is proposed that optimizes delaying transmissions in order wait (thus trading end-to-end delay and/or throughput). In addition, exploits frequency-dependent radiation pattern transducers reduce communication consumption. Our implemented evaluated through emulations, showing improved performance over some well-known geographic routing solutions delay-tolerant networking solutions.
