Research On Underwater Acoustic Network Verification System Based On B/S Architecture

In the marine development,communication is the bridgehead of the intelligent age,so it is very important for our country to master the underwater acoustic communication technology.As an important part of underwater acoustic communication technology research,underwater acoustic network can further promote the research of underwater acoustic communication and realize the interconnection of everything in the marine world.Underwater acoustic network protocol is the foundation of underwater acoustic network.Generally,the research of underwater acoustic network protocol is divided into three stages: software simulation,hardware simulation and real node ocean test.In order to accelerate the research of underwater acoustic network protocol,this paper has designed and implemented an underwater acoustic communication network verification system based on B / S architecture.The system has used ns-3 to realize the software simulation and hardware simulation of underwater acoustic communication.It has used real underwater acoustic nodes(ARM board and acoustics communication machine)to realize real node testing,and used B / S architecture to realize remote connection and control.In order to design and implement the system,this article has mainly done the following three parts of work: First,based on TCP / IP,this paper has designed and implemented a custom data packet format and a software framework to parse the data packet by C++ and Python.Second,based on the framework,this paper has realized the four major components for this system:(1)a ns-3 virtual underwater acoustic network node(ns-3 VUAN node)was designed;(2)a real underwater acoustic network node(RUAN node)was designed by using the "ARM board + communicator";(3)designed the system external interface-Web server;(4)designed UAN server which was an administrator to manage the VUAN node,RUAN node and Web server.Third,by conceiving three experimental scenarios,three production experiments were carried out:(1)this paper has down the point-to-point software simulation experiment,networking software simulation and hardware simulation based on ns-3;(2)this paper has finished real node hardware Simulation experiment;(3)this paper has checked and analyzed the link of this system.The final analysis proves that the system is a stable,reliable,and efficient comprehensive platform,and is a platform on which software simulation,hardware simulation and real node field test can be realized.
