Design And Implementation Of Wireless Sensor Network Virtual Laboratory Based On Microservice Architecture

Wireless sensor network technology is very important.It is a key component of the Internet of Things.With the advancement of technology,it has great application value in the fields of military,medical,industrial and social life.For the field of wireless sensor network technology,many colleges and universities have already set up relevant experimental courses to improve students' professional knowledge and practical ability.However,wireless sensor network nodes have limited energy resources,and communication between sensors is limited by geographical environment interference,which makes teaching simulation experiments difficult.With the continuous development of experimental environment problems in colleges and universities,the emergence of virtual laboratories has brought great convenience to experimental teaching work.With the development of colleges and universities,the increasing number of users will bring an increasing number of visits,which will bring great pressure to the traditional laboratory background.The coupling between the submodules of the background project becomes more and more tight as the project increases.This will seriously affect the operation,maintenance and expansion of the virtual laboratory.To this end,this paper designs a set of virtual laboratory system based on micro-service architecture based on the current mainstream solution ideas by using the characteristics of low-coupling,lightweight,and high autonomy of micro-service architecture.The main work is as follows:(1)Introduced the project using j2 EE architecture and using MVC mode combined with SpringCloud,SpringBoot,SSH(spring,springMVC,Hibernat),JQuery and other technologies to build a virtual laboratory,expounding the principles of these technologies and their role in the project.(2)The simulation platform adopts Castalia as the framework for constructing simulation events.It is based on the OMNeT++ platform,which is used to solidify the general part of the simulation algorithm,so that students only need to pay attention to the experimental protocols and algorithms.(3)The functions of each service module are analyzed and designed in detail.(4)Realize the configuration of the micro-service concept in the system architecture,listed some main codes for setting up the virtual laboratory and the teststructure of simulation experiment,with screenshots.Through the above points,it brings great help to the wireless sensor simulation teaching experiment,and also improve the experimental efficiency of students.
