ns-3
Bug List
Class ns3::Ns2MobilityHelper

Traces that generate initial position statements at the end of the mobility file (e.g. SUMO TraceExporter) will not be read correctly. The workaround is to relocate these three initial position statements to the beginning of the trace. See https://www.nsnam.org/bugzilla/show_bug.cgi?id=1316

Rounding errors may cause movement to diverge from the mobility pattern in ns-2 (using the same trace). See https://www.nsnam.org/bugzilla/show_bug.cgi?id=1316
