Aqua-Sim: An NS-2 based simulator for underwater sensor networks

TLDR

Aqua‑Sim builds on NS‑2, a widely used network simulator, and adopts an object‑oriented design. The paper introduces Aqua‑Sim, a network simulator for underwater sensor networks. Aqua‑Sim is implemented as a set of NS‑2 classes that model underwater acoustic channels, collision behavior, three‑dimensional deployment, and a suite of basic and advanced protocols. Case studies show that Aqua‑Sim reproduces real‑world underwater sensor network behavior with high fidelity and flexibility.

Abstract

In this paper, we present a network simulator, Aqua-Sim, for underwater sensor networks. Aqua-Sim is based on NS-2, one of the most widely used network simulators, and it follows object-oriented design style and all network entities are implemented as classes. Aqua-Sim effectively simulates the attenuation of underwater acoustic channels and the collision behaviors in long delay acoustic networks. Moreover, Aqua-Sim supports three-dimensional network deployment and provides a rich set of basic and advanced protocols. Through several case studies, we show that Aqua-Sim can "reproduce" the real world with high fidelity and flexibility.
