Subject: [ns] How to patch GPSR routing protocol to ns-2.35
To: ns-users@isi.edu
Message-ID: 34541231.p...@talk.nabble.com
Content-Type: text/plain; charset=us-ascii
Hi,
I have patched GPSR to ns-2.35 using keliu' code. It works fine with given
tcl file. I need to move nodes according to mine own mobility scenario and
compare them to AODV protocol.
I have two problems
1. I don't understand what this command in gpsr.tcl file means
proc gpsr-create-mobile-node { id args } {
.
if [info exists opt(energy)] {
$node addenergymodel [new $opt(energy) $node 10 0.5 0.2]}
.
What are these figures (0.5, 0.2), are these energy consumed in reception
and transmission or some thing else.
Secondly I want move mobile node created using proc defined in gpsr.tcl file
according to my own mobility plan e.g.
$ns_ at 0. $node_(0) setdest 144.816950690450 20.073824649527
0.324133202939
$ns_ at 0. $node_(1) setdest 93.957720171475 192.140808646867
1.452613500562
$ns_ at 12.158688172971 $node_(23) setdest 113.137798368154 39.443538618334
0.902003496971
$ns_ at 14.805074599534 $node_(2) setdest 152.227654369397 20.766089279052
1.742469780423
But when I run simulation it gives error like this:
Load complete...
Starting Simulation...
ns: _o18 setdest 144.816950690450 20.073824649527 0.324133202939:

Urgent help is needed please
