Aqua-Sim Next Generation

Through the use of network simulators we are able to test and examine different combinations of protocols in low cost and controlled environments. To ensure the accuracy of these simulators it is crucial that they consistently expand and enhance their modules to offer extensive support. In this paper, we introduce Aqua-Sim Next Generation, an NS-3 based underwater sensor network simulator. This work is an expansion of Aqua-Sim, transferring to the newer core simulator, NS-3, for enhanced memory management and performance. Additionally, we revitalize legacy supported protocols through better packet handling and header usage. Aqua-Sim Next Generation offers real-world features to close the gap between simulation and real-system tests while providing additional modules for easier user development. With the goal to create a more efficient and functional simulator, we improved Aqua-Sim's architecture. Furthermore, we integrate a specialized underwater information-centric module to assist in simulating innovative techniques in underwater sensor networks. Experimental results show that Aqua-Sim Next Generation runs twice as fast compared with Aqua-Sim while showing large increases in memory management.
