aomdv_ns2.35

[Soorya]

This is a part of  aomdv.tcl on ns2.35 to reate trace object for ns, nam. Why certain lines are commented here? When I am  running aomdv.tcl , I am getting output on the terminal but 'the animator NAM' is not displaying . How can I view the output of aomdv on nam?

                      set nsTrc [open ns.trc w]

                      $ns trace-all $nsTrc
                    # set namTrc [open nam.trc w]
                    # $ns namtrace-all-wireless $namTrc $val(x) $val(y)
                      set scenarioTrc [open scenario.trc w]

                        proc fileTrace {} {

                                #  global ns nsTrc namTrc
                                   global ns nsTrc scenarioTrc
                                   $ns flush-trace
                             

                                  close $nsTrc
                                  close $scenarioTrc
                              #  close $namTrc
                             #  exec nam nam.trc &
                      }

Hi.

I want to implement energy efficient aomdv in mobile adhoc network. I have found several aomdv examples. which one is the basic aomdv protocol where I can do the modifications? And when I run aomdv.tcl , nodes are just displayed on animator ,nothing else.Is this the correct output of aomdv.tcl?

[knudfl]

"aomdv.tcl" : A template with no traffic / no communication.

The included feature is section  # Tracing ....

   314  # ------------------------------------------------------------------------------
   315  # Tracing
   316  # ------------------------------------------------------------------------------
   317
   318  # printing simulation time

[SOORYA V NAIR]

What mofification is to be done in aomdv.tcl for adding traffic/communication between nodes.

--

[knudfl]

Actually it's no secret how to achieve communication : Just run the examples. And read the examples, please.

E.g. eshete-aomdv2.tcl shows communication in NAM.

....  And in the trace file `ns.trc´ →

$ awk -f all-2.awk ns.trc
cbr s:59831 r:208, f:76256
avg_end_to_end_delay: 0.4355
Packet Delivery ratio: 0.3476
Packet Drop ratio: 0.9965

Analyzing scripts https://drive.google.com/drive/folders/1rU_MFAEl1GCLMTJPLR3zbxPxkQQHkQ7T?usp=sharing

There is also "communication" in aomdv.tcl :

$ awk -f all-2.awk ns.trc
cbr s:161954 r:152364, f:344124
avg_end_to_end_delay: 0.0537
Packet Delivery ratio: 94.0786

Ok..Thank you

Sir,

Is 'eshete-aomdv2.tcl ' a basic aomdv with mobility only?Is mobility is the only difference between aomdv.tcl and eshete-aomdv2.tcl?Can I take eshete-aomdv2.tcl as the basic model to implement energy efficiency in manet?

Thank you sir...Does ns2 has Patricle swarm optimization algorithm for finding energy efficient routes?

[knudfl]

@Soorya ,   Hi.

Particle swarm optimization :   Do you mean something like "AntHocNet" ?

[SOORYA V NAIR]

Sir,

In my paper they have mentioned that Particle swarm optimization is used to find the fitness funtion such as energy and to optimize routes.Does ns2 has its implementation?

[SOORYA V NAIR]

Sir ,

Also I want to know how to find routes from a source to destination in a mobile network.since nodes are moving ,how can I find the paths to a particular destination in a mobile adhoc network?

[SOORYA V NAIR]

Sir,

Can you please tell me how can I route traffic to a destination node in mobile adhoc network?Since nodes are moving how we can find paths between a source and destination after adding mobility to the network?

[knudfl]

@Soorya.

? Tracking location of a moving mobile unit ?

That's what GPS is used for.  Probably nothing for the ancient ns2  ? ? ?

?   https://www.google.com/webhp?hl=all&gws_rd=ssl#hl=en&q=simulate+gps

[SOORYA V NAIR]

Sir,

I have read that in AOMDV if the network is static we can send packets from source to destination and find the multiple paths between source and destination.While if we add mobility to the network then how it will work?How can we find the routes  that exist between source and destination?

[knudfl]

@Soorya ,   Hi.

Assume you know the source location ... if stationary, not mobile / moving.

Destinations with various moving locations :  In the real world I'd vote for GPS location.  What else have you imagined ?

[SOORYA V NAIR]

Sir,Is there any code  for energy efficient routing in manet in ns2?

[SOORYA V NAIR]

Sir,

I am getting the error  "can't read "node_(0)": no such variable" while I was trying to add mobility.I set the no.of nodes as 5 and defined for loop from 0 to <val(n) .Parts of my code is given below.Can you help me to resolve my error.

-------------------------------------------------------------------------------------------------

set val(rp) AOMDV  ;                                # routing protocol
set val(n) 5.0 ;

-------------------------------------------------------

for {set i 0} {$i < $val(n) } {incr i} {
    set node($i) [$ns node]
    $node($i) random-motion 0;                 # disable random motion
}

$ns at 0.7 "$n(2) setdest 27.3 227.4 10000.0"
$ns at 5.0 "$n(3) setdest 20.05 3.98 10000.0"
$ns at 0.0 "$n(4) setdest 30.8 435.3 10000.0"

-----------------------------------------------------------------------------------------------------

for {set i 0} {$i < $val(n) } {incr i} {
        $ns at $val(end) "$node($i) reset";
}

   

[knudfl]

Well, then please attach your files. Simulation, movement file etc.

Your nodes are defined as   n(0) ... n(X) .

The error seems to be that somewhere you are asking for n(0), but the code text is node_(0).

[Soorya]

Thanks for your reply sir.I corrected the name from n (0) to node(0).But now I am getting the following error.I have attached my tcl file here.

num_nodes is set 5

@Soorya.

The file name cannot be `aomdv.tcl´ . There can be only one file with that name.
Please always use new unique names for new files.

Your errors :  Seems to be something wrong with this :
set val(dim) [expr $val(n) / $val(density)]
set val(x) [expr [expr sqrt($val(dim))] * 1000]
set val(y) [expr [expr sqrt($val(dim))] * 1000]

No issues when using  a fixed setting :

set val(dim) [expr $val(n) / $val(density)]
set val(x) 500
set val(y) 500

Dear Kundfl

please could help me how to find the best path in AODV routing protocol based on higher residual energy node and minimum hop count please if you can send me the source code to do that. Your help would be appreciable. Dear Kundfl  I am working on ns.2.35

Best Regards,

[knudfl]

Hints, hop count.   From my notes ....

[SOORYA V NAIR]

Thank you sir,it worked.

[SOORYA V NAIR]

Sir,

I have initialized the energy as  100 jules for all the nodes in manet.Now I want to calculate the energy consumption for each route in the aomdv protocol.How can I find all the routes in the routing table?Also I have an algorithm for selecting the best  path with less energy consumption?Is it in the aomdv.cc file I need to implement the algorithm?

[SOORYA V NAIR]

Sir tcp or udp is preferred transport protocol in manet?

Ok thank you sir

[SOORYA V NAIR]

Hi sir,

 I have aomdv code which calculate energy consumption.While I run the program I  am getting paths with energy values.How can I compare these paths to find out path having highest energy?

[SOORYA V NAIR]

Sir,

 Whether a node can transmit packets after its enegy become 0?
