When estimating the spatial coherence of underwater acoustic signals, the estimator characteristics depend heavily on the estimation method (e.g., based on spectral coherence or on cross correlation) and its parameter settings. We address this issue

The realization of centralized communication strategies underwater is very cost-intensive and not feasible due to the partly scattered network nodes. Each node must be able to distribute its messages directly. This chapter deals with different approa

What can be adjusted in-mission to maintain stable communication and how can it be done? This chapter first lists the important parameters. For example, adjusting the transmission power based on distance, or varying the data rate vs required robustne

For remote deployment of unmanned/autonomous underwater vehicles that, for reasons of size, power usage and cost, communicate acoustically in relatively high frequency bands, a backbone underwater acoustic network needs to support multiple frequency

An underwater acoustic network simulation methodology is presented that is based on lookup tables (LUTs) with physical-layer error ratios. These LUTs are prepared with a validated replay channel simulator, which is here driven by channel measurements

This paper discusses validation methods for underwater acoustic communication channel simulators, and validates direct and stochastic replay of underwater acoustic communication channels as implemented in a channel simulator called Mime. Direct repla
