[ns] counting the number of packets sent during the simulation

[anas abu_taleb]

Hi all
   
  I am using ns-2.29 and as part of my research I am trying to count the number 
of packets sent by a node. 
   
  I added a method called counting to count the number of packets to the source 
code of the UDP agent ( I wonder if this is the right place). And what I want 
after that is to calculate  the number of packet at some time during the 
simulation this is as example of what I did: 
   
  set udp_(0) [new Agent/UDP]
$ns_ attach-agent $node_(0) $udp_(0)
set null_(0) [new Agent/Null]
$ns_ attach-agent $node_(1) $null_(0)
  set cbr_(0) [new Application/Traffic/CBR]
$cbr_(0) set packetSize_ 512
$cbr_(0) set rate_ 81920
$cbr_(0) set random_ 1
$cbr_(0) set maxpkts_ 1
$cbr_(0) attach-agent $udp_(0)
#$ns_ link_lossmodel $val(err) $node_(0) $node_(1)
$ns_ connect $udp_(0) $null_(0)
$ns_ at 0 "$cbr_(0) start"
$ns_ at 90 "$cbr_(0) stop"

  if { [$ns_ at 5 "$udp_(0) counting"] < 120 } {
 set x_coor [$node_(0) getX]
 set y_coor [$node_(0) getY]
 $node_(4) setdest $x_coor $y_coor 15.0
 }
   
  However the code is working fine but it is not recognizing the condition in 
the if statement. 
   
  I will be grateful for your help

[ns] energy model variables

[anas abu_taleb]

Hi all
   
  I am trying to access the value of the initial energy for the energy model 
after configuring the nodes. for example after 
   
  $ns_ node-config -adhocRouting $val(rp) \
  -llType $val(ll) \
  -macType $val(mac) \
  -ifqType $val(ifq) \
  -ifqLen $val(ifqlen) \
  -antType $val(ant) \
  -propType $val(prop) \
  -phyType $val(netif) \
  -topoInstance $topo \
  -agentTrace OFF \
  -routerTrace OFF \
  -macTrace ON \
  -movementTrace OFF \
-energyModel "EnergyModel" \
-initialEnergy 3 \
-rxPower 0.3 \
-txPower 0.3 \
-IDLE 0.3 \
  -channel $chan_1_ 
  #-errProc UniformErr
  #-IncomingErrProc UniformErrorProc
  #-IncomingErrProc $val(err)
   
  for {set i 2} {$i < $val(nn) } {incr i} {
set node_($i) [$ns_ node] 
 $node_($i) random-motion 0  ;# disable random motion
}
   
   
  I want to check the initial energy using an if statement 
   
  if {$initialEnergy > 2} { DO WHATEVER} 
   
  I will be grateful for your help 
  Regards
  Anas

[ns] LEACH total energy consumpsion

[anas abu_taleb]

Hi 
  Finally I managed to run leach under ns-allinone-2.29. Unfortunatelly, when I 
ran the example script the output said that the total energy comsumed is equal 
to 367.6739273 ... etc. but this doen not look right as the every node has 2 
joules as initial energy and if you run the simulation for 100 nodes this mean 
that the total initial energy is 200. so how come the totat energy consumed is 
larger than the total initial energy?
   
  Please help me to solve this problem and if the output is correct could you 
please provide me with an explanation for that and I will be grateful.
   
  Regards
  Anas

[ns] ns-leach extesion problems

[anas abu_taleb]

Dear Sir 
   
  I am using ns-2.31 under cygwin and I have been trying to extend it
 with the leach extension 
  developed for ns-2.27. 
   
  after following the procedure specified in the pfd document that
 comes with it I got the following error:
   
  trace/trace.cc: In static member function `static int
 Trace::get_seqno(Packet*)'
:
trace/trace.cc:206: error: `PT_XCP' undeclared (first use this
 function)
trace/trace.cc:206: error: (Each undeclared identifier is reported only
 once for
 each function it appears in.)
trace/trace.cc: In member function `virtual void
 DequeTrace::recv(Packet*, Handl
er*)':
trace/trace.cc:567: warning: int format, nsaddr_t arg (arg 5)

trace/trace.cc:586: warning: int format, nsaddr_t arg (arg 6)
make: *** [trace/trace.o] Error 1
   
  I do not know what is wrong, and I wonder if I have to install
 ns-2.27, but I tried to install it but it did not work. 
   
  I am grateful for your help
  Regards
  Anas
