The 2020 Workshop on ns-3 (WNS3 2020) is the twelfth edition of an annual series of workshops around the discrete-event network simulator known as "ns-3". The workshop aims to gather ns-3 users and developers, together with networking simulation practitioners and users, and developers of other network simulation tools, to discuss the ns-3 simulator and related activities. ns-3 is a tool used for performance evaluation in computer networks, and this workshop offers a venue for those involved with extending or testing the tool itself to publish original work in this regard. The workshop is sponsored by the ns-3 Consortium and organized in conjunction with training sessions, the Consortium Annual Meeting, and developer discussions.
