Explanation of the test scripts included in the distribution of the PCF implementation for ns-2.


pcftest.tcl :

This test script simulates a number of nodes sending constant bit rate (CBR) flows
to a sink located outside the wireless LAN. There can be a variable number of nodes
(with one CBR flow for each node), and the number of nodes to received higher
priority (i.e. get polled during the CFPs), and the duration of a superframe can be
specified.

To run this test script (after having patched ns to include support for PCF), the
syntax is

ns pcftest.tcl <nodes> <prionodes> <cbrinterval> <cbrsize> <outfile> <superframe>

where <nodes> is the number of nodes the simulation should contain, <prionodes> is
the number of nodes that should be polled (it will be the <prionodes> first nodes
that will be prioritized), <cbrinterval> is the interval between packets generated
by the CBR sources, <cbrsize> is the size of each packet (in bytes) generated by the
CBR sources, <outfile> is the filename the (gzipped) tracefile should be written to,
and <superframe> is the length of the superframe in Time Units (TU) (1 TU = 1024
us).
