Hi Matthias,
My simulation settings are:
set val(chan) Channel/WirelessChannel
set val(prop) Propagation/TwoRayGround
set val(netif) Phy/WirelessPhy
set val(mac) Mac/802_11
set val(ifq) Queue/DropTail/PriQueue
set val(ifqlen) 50
set val(ll) LL
set val(ant) Antenna/OmniAntenna
set val(adhocRouting) AODV
set opt(energymodel) EnergyModel
set opt(initialenergy) 1000
set opt(idlepower) 1.0
set opt(rxpower) 1.0
set opt(txpower) 1.0
set opt(sleeppower) 0.001
set opt(transitionpower) 0.2
set opt(transitiontime) 0.005
$ns_ node-config -adhocRouting $val(adhocRouting) \
-llType $val(ll) \
-macType $val(mac) \
-ifqType $val(ifq) \
-ifqLen $val(ifqlen) \
-antType $val(ant) \
-propType $val(prop) \
-phyType $val(netif) \
-topoInstance $topo \
-agentTrace ON \
-routerTrace ON \
-macTrace ON \
-channel $chan_6_ \
-numif 1 \
-energyModel $opt(energymodel) \
-idlePower $opt(idlepower) \
-rxPower $opt(rxpower) \
-txPower $opt(txpower) \
-sleepPower $opt(sleeppower) \
-transitionPower $opt(transitionpower) \
-transitionTime $opt(transitiontime) \
-initialEnergy $opt(initialenergy)
The first question I am trying to answer is how long can the network
survive before all available energy is expended.
Then I want to extend the simulation, so that:
* Energy can be recharged
* Nodes stop once their energy is expended. No more transmissions are
allowed, etc.
Then I can see how the network might reform itself around "dead zones",
etc. before moving on (possibly) to some of the energy aware routing
enhancements.
