*hello friends,
i want to simulate various wireless scenario, here some lines of tcl script
to access different wireless scenario:*
set mode DCF ;# mode for this test DCF/PCF
set pcf_period 0 ;# CFP period for pcf mode
set pcf_duration 0 ;# CFP duration for pcf mode
set endtime 15.0 ;# duration of the simulation
set title_ "snenario-test" ;# default title for the
scenario
set idea_mac 0 ;# default cleverness of mac
;# 0 - normal
;# 1 - persistent slotting
;# 0 - PDCF
set val(chan) Channel/WirelessChannel ;# Channel Type
set val(prop) Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
set val(mac) Mac/802_11 ;# MAC type
set val(ifq) Queue/DropTail/PriQueue ;# interface queue type
set val(ll) LL ;# link layer type
set val(ant) Antenna/OmniAntenna ;# antenna model
set val(ifqlen) 50 ;# max packet in ifq
set val(rp) DSDV ;#
set val(x) 50
set val(y) 50
Phy/WirelessPhy set CPThresh_ 2000
Phy/WirelessPhy set per_ 0.0
Mac/802_11 set bandwidth_ 36Mb
PLevels set max_plevels_ 8
PLevels set plevels_ 8
MAC_MIB set RTSThreshold_ 3000
MAC_MIB set ShortRetryLimit_ 7
MAC_MIB set LongRetryLimit_ 4
PHY_MIB set MinimumBandwidth_ 6Mb
PHY_MIB set SlotTime_ 0.000009
PHY_MIB set SIFS_ 0.000016
.....
......
......
*i got following error:-*
$ ns main.tcl
invalid command name "PLevels"
while executing
"PLevels set max_plevels_ 8"
*what is this error for????
plz help me*
