Impact of ARQ on the Distortion Performance of Underwater Acoustic Mobile Networks

Abstract

The paper considers the route distortion for underwater acoustic mobile networks consisting of autonomous underwater vehicles (AUV’s). The AUV’s transmit the information along a multihop route through the network. The simple stop and wait automatic repeat request (ARQ) protocol is implemented on a hop-by-hop basis. The mobility model is direction persistent. Each AUV-to-AUV channel experiences frequency dependent path loss, Ricean fading and interference. Numerical examples are presented to demonstrate the impact of ARQ on the average route distortion.
