# Note that 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.
#
# One of the transmitter applications runs outside the simulation, on
# the host, and sends messages to the AP through the FdNetDevice/TAP
# link.
