Abstract--We address several inter-related aspects of underwa-
ter network design within the context of a cross-layer approach.
We first highlight the impact of key characteristics of the acoustic
propagation medium on the choice of link layer parameters; in
turn, the consequences of these choices on design of a suitable
MAC protocol and its performance are investigated.
Specifically, the paper makes contributions on the following
fronts: a) Based on accepted acoustic channel models, the point-
to-point (link) capacity is numerically calculated, quantifying
sensitivities to factors such as the sound speed profile, power
spectral density of the (colored) additive background noise and
the impact of boundary (surface) conditions for the acoustic
channel; b) It provides an analysis of the Micromodem-like link-
layer based on FH-FSK modulation; and finally c) it undertakes
performance evaluation of a simple MAC protocol based on
