Abstract

This letter minimizes outage probability in a single decode-and-forward (DF)\nrelay-assisted underwater acoustic network (UAN) without direct\nsource-to-destination link availability. Specifically, a joint global-optimal\ndesign for relay positioning and allocating power to source and relay is\nproposed. For analytical insights, a novel low-complexity tight approximation\nmethod is also presented. Selected numerical results validate the analysis and\nquantify the comparative gains achieved using optimal power allocation (PA) and\nrelay placement (RP) strategies.\n
