This paper investigates the delay-reliability tradeoff for multihop underwater acoustic networks. The propagation med-ium of underwater acoustic channel exhibits distinct characteristics when contrasted with other common propagation media such as copper, fiber, and radio. In particular there are the extremely slow propagation speed of sound in water, high signal attenuation due to absorption, significant delay spreads and intersymbol interference, and range-dependent transmission bandwidth. These features make the delay-reliability tradeoff for underwater acoustic channels fundamentally different from other channels. The approach is based on error-exponents which enable a physical-layer comparison of multihopping versus no hops while considering the overall throughput. The analysis shows that for typical network parameters, increasing the number of hops dramatically improves both the achievable information rate and the achievable reliability function, which quantitatively captures the decay rate of the decoding error probability as the coding block length increases asymptotically. Numerical results are presented to illustrate the analysis.
