LEcture 6 - Ns2 Energy Model Wireless NEtworking in ns2 By default, nodes have infinite energy, to make it finite, we need to implement energy model. in the node config we need to include the following lines -energyModel "EnergyModel" \ -initialEnergy 3.0 \ -txPower 0.9 \ -rxPower 0.5 \ -idlePower 0.45 \ -sleepPower 0.05 \ Energy (joules) = Power (Watts) * Time (sec) www.nsnam.com for downloading the source codes Also subscribe to my youtube channel www.youtube.com/tspradeepkumar Thanks for watching.

This post shows the wired network coding in ns2. It uses 6 nodes ( 0 to 5) and exchange FTP/CBR packets between the nodes. Please find the coding here.  Wired Network Wired Coding in ns2 (with comments and explanation, for detailed explanation see the video at the end) #please subscribe #www.youtube.com/tspradeepkumar #Thank you #create a simulator object  set ns [new Simulator] #create a trace file, this file is for logging purpose  set tracefile [open wired.tr w] $ns trace-all $tracefile #create a animation infomration or NAM file creation set namfile [open wired.nam w] $ns namtrace-all $namfile #create nodes set n0 [$ns node] set n1 [$ns node] set n2 [$ns node] set n3 [$ns node] set n4 [$ns node] set n5 [$ns node] #creation of link between nodes with DropTail Queue #Droptail means Dropping the tail. $ns duplex-link $n0 $n1 5Mb 2ms DropTail $ns duplex-link $n2 $n1 10Mb 5ms DropTail $ns duplex-link $n...
