In this paper, we first present an analytical framework based on a queueing system that evaluates communication performances of underwater acoustic sensor networks (UASNs), where each underwater sensor distributed within a 3-dimensional (3D) space under sea surface performs fountain code (FC)-based automatic repeat request (ARQ) transmissions under the slotted ALOHA medium access control protocol. Under the proposed framework, we evaluate communication performances given in terms of successful FC-based ARQ transmission probability and the average queueing delay of an underwater sensor. Further, our analysis can formulate an optimization problem that aims at minimizing total cost occurred to install and operate 3D UASNs, without compromising two communication QoS requirements. To solve this problem, we propose a recursive algorithm to approach an optimal solution in reasonable time.
