Wireless LAN Power Management Extension for ns-2

Wireless LAN (IEEE 802.11) power management extension. (Website)
This supports legacy power save functions defined with IEEE 802.11.

Features

• Supports legacy power management functions defined with IEEE 802.11.


• Supports PS-Mode AP and STA in infrastructure mode.


• Supports calculation of power consumption of each nodes.


• Based on ns-2.33.

How to use
See sample script at: tcl/ex/powersave.tcl

Access point node can be configured with DTIM period by the following command.

$mac_(ap_node) set DTIMPeriod_ 1
STA node can be configured as PS-Mode by the following command.

$mac_(sta_node) set isPowerSave_ true
To setup the power configuration, use $ns node-config parameters like as:

$ns_ node-config .... \
-txPower 0.660 \
-rxPower 0.395 \
-idlePower 0.035 \
-sleepPower 0.001 \
-initialEnergy 1000
After simulation, you can show the remaining node energy by the following command:

puts [$node_(sta_node) energy]
You can check node behaviors with nam tool.
