[Smac-users] SMAC vs 802.11

[salehma@aston.ac.uk]

Hi everyone

I've been trying for a while to compare the energy consumption of the
802.11 (in  ad-hoc mode)and the SMAC protocol.

Dr Wei Ye I've read your paper on the "An Energy-Efficient MAC Protocol
for Wireless" and wish to conduct an experiment to compare the SMAC with
802.11(ad-hoc mode), your paper has shown the difference when there was no
sleep mode for the 802.11. I wish to get results for the

-idlePower
 -rxPower
 -txPower
 -sleepPower

+ the total power consumed.

I've come across the simulation script of Vijay Kakadia (as below)

set opt(chan)		Channel/WirelessChannel
set opt(prop)		Propagation/TwoRayGround
set opt(netif)		Phy/WirelessPhy
#set opt(mac)            Mac/802_11                   ;# MAC type
set opt(mac)            Mac/SMAC                   ;# MAC type
set opt(ifq)		Queue/DropTail/PriQueue
set opt(ll)		LL
set opt(ant)            Antenna/OmniAntenna

set opt(x)		800	;# X dimension of the topography
set opt(y)		800		;# Y dimension of the topography
set opt(cp)		"../mobility/scene/cbr-50-10-4-512"
set opt(sc)		"../mobility/scene/scen-670x670-50-600-20-0"

set opt(ifqlen)		50		;# max packet in ifq
set opt(nn)		2		;# number of nodes
set opt(seed)		0.0
set opt(stop)		700.0		;# simulation time
set opt(tr)		MyTest.tr	;# trace file
set opt(nam)		MyTest.nam	;# animation file
set opt(rp)             DumbAgent       ;# routing protocol script
set opt(lm)             "off"           ;# log movement
set opt(agent)          Agent/DSDV
set opt(energymodel)    EnergyModel     ;
#set opt(energymodel)    RadioModel     ;
set opt(radiomodel)    	RadioModel     ;
set opt(initialenergy)  1000            ;# Initial energy in Joules
#set opt(logenergy)      "on"           ;# log energy every 150 seconds

set b [$node_(0) set mac_(0)]
#set c [$b set freq_]

#set e [$node_(0) set netif_(0)]

#puts $tracefd "M 0.0 prop $opt(prop) ant $opt(ant)"
#puts $tracefd "V $b : $c : $d :"
puts "Starting Simulation..."
$ns_ run

This allows me to view the energy for SMAC (in the tracefile), I've also
came to understand this trace file (from reading the NS manual). but I
wish to compare this with the 802.11 ad-hoc mode, would any be willing to
share this ? Or if there are any tips on how I may alter the above
simulation script to accomadate the 802.11 please share.

I would really appreciate any help that im to get as I have no experience
with NS2 beforehand.

Thanks ppl.
