All-terminal reliability of multi-AUV cooperative systems in horizontally stratified SOFAR channel

ABSTRACT

This work develops a calculation method of all-terminal reliability for multi-AUV cooperative systems in horizontally stratified sound fixing and raging channel (SOFAR channel), considering the sound speed profile in SOFAR channel. The working environment of multi-AUV (autonomous underwater vehicle) cooperative systems is complex and the reliability under different environmental conditions is different. This work adopts the Kraken normal mode method to get the transmission loss, and calculates the reliability of the communication link based on the relationship between the transmission loss and signal-to-noise ratio. All-terminal reliability of multi-AUV cooperative systems can be obtained.
