SNetSim is a event-driven simulation software running on Windows based operating systems. It's being developed in Naval Science and Engineering Institute (Istanbul , Turkey) It's free for your academical works. If you use it for your documented studies, please remember to reference to our web site. We do not provide the source code for the time being. Because, we are planning to complete coding some basic functions and recover from the bugs after receiving reports from users. But, our goal is to make the source available, after the software is coded clearly and well-documented to be used by any researcher who wants to customize it for his needs. For now, feel free to download and use the executable software. We are looking forward to receiving feedback from you. Please send your e-mails to feedback to SNetSim.
