In this way, you can collect all the application instances and then generate a random number and decide which application instance to start first using the StartApplication method and a specified time point.</div><div class=""><br class=""></div><div class="">You can schedule any actions that you would like your application to take as NS3 events in the code of your application.</div><div class=""><br class=""></div><div class="">Hope that this helps.</div><div class=""><br class=""><div class="">
