# Note: To run this experiment you need to have a PlanetLab account.
#
# This experiment consists of a simulated wireless sensor network (ns-3)
# with one fixed access point (AP), running an agent application, and several
# mobile stations that run a transmitter application to send messages to
# the AP.
#
# The same experiment described above is run in parallel with different
# number of mobile stations in 2 PlanetLab hosts.
