Ns-2 and its successor ns-3 are discrete-event simulators. Ns-
3 is still under development, but offers some interesting characteristics
for developers while ns-2 still has a big user base.
This paper remarks current differences between both tools
from developers point of view. Leaving performance and resources
consumption aside, technical issues described in the
present paper might help to choose one or another alternative
depending of simulation and project management requirements.Ministerio de Educación y Ciencia TIN2006-15617-C03-03Junta de Andalucía P06-TIC-229
