Hi. Well, if the authors haven't specified it, the only solution will be to get in touch with them and inquire. 

I have worked only with NS-3 on 802.11g/n and there are a variety of protocols to choose from. You can look it up in the online manuals. 

Hope this helps.

With thanks for your attention  Mr. Srikant Manas Kala

I tried to communicate with the authors but have not received any response from them. I know what protocols in ns2 available, but do not know which to choose so I could get the results in the paper

That's tricky. If the authors have compared their work/approach with some pre-existing work, you could look up that reference.

This paper covers some attacks and suitable routing protocols to prevent/mitigate them. 

Check it out.

Thank you for your guidance, I use it.

Dear Maryam

            If it is not mention that means the proposed attack model is general and can be applied with most routing protocols. Normally the authors use the protocols who's source code is available as an example in simulators.

          The best thing is to install the simulator NS  and see the example WSN scenarios and available souse code.

         If you are interested in WSN or BASN security i would suggest to install Castalia a module of OMNET++ that has routing protocols examples 

 You may have a look at my papers on RG profile related to security in MANET ans WSN.

Thanks for your help Dr Adnan Nadeem

I am using NS2 simulator .

I read the article again today with more accuracy and I saw in part of it was written about the network model  : " In the network model, a WSN with N sensor nodes is considered, which can be denoted by a directed graph G = (V, E). In this graph, V is the set of vertices indicating the sensor nodes and E is the set of direct edges indicating the wireless links in the graph. The graph takes a Unit Disk Graph (UDG) as its connectivity model" .

Is this network model refers to the network protocol or is used on the network topology?

how can I show this network model in NS2?

Hi, 

G represents network topology.

A UDG essentially means that  each vertex represents the center of a unit disk/circle and  two vertices can communicate when their "unit disks" overlap. A successful transmission would be between nodes that are  upto 2 x Radius_disk (or diameter of disk) apart as in that scenario the two disks will share a tangent. These "wireless links" will be represented by an edge. The graph consists of these vertices and edges.

Look for MobilityHelper (we have that in ns-3) through which you can set the positions of nodes or allocate them randomly through UniformDiscPositionAllocator, and then use a constant position model if your network is static (ConstantPositionMobilityModel).

Hope this help. Google, you will find some scripts. Tailor them to suit your model.

Hi  Mr Srikant Manas Kala

Thank you for your detailed explanation about this network model. I will use the points you have mentioned, they were very useful for me.

I do more search for graph script , but unfortunately I did not find any useful script for it yet.

 This is an ns-3 script that uses a grid allocator. You can use the unit disk allocator instead by following the example. 

Hope this helps.

For parameters and specifications, you may refer to my research work. I always include an elaborate table specifying network specs and simulation parameters. 

thanks for your kindness, Mr Srikant Manas Kala 

my simulation language is Tcl. For this, Understanding the script you sent to me a little difficult for me but I would all their efforts to be able to use it.

With special thanks.

Happy to help. All the best.

Hi

The following code may be useful for beginners in NS2.

Try this. its an example for wired network simulation.  you can find examples of wireless network also.

#Create a simulator object

set ns [new Simulator]

#Tell the simulator to use dynamic routing

$ns rtproto DV

#Open the nam trace file

set nf [open out.nam w]

$ns namtrace-all $nf

#Define a 'finish' procedure

proc finish {} {

global ns nf

$ns flush-trace

#Close the trace file

close $nf

#Execute nam on the trace file

exec nam out.nam &

exit 0

}

#Create seven nodes

for {set i 0} {$i < 7} {incr i} {

set n($i) [$ns node]

}

#Create links between the nodes

for {set i 0} {$i < 7} {incr i} {

$ns duplex-link $n($i) $n([expr ($i+1)%7]) 1Mb 10ms DropTail

}

#Create a UDP agent and attach it to node n(0)

set udp0 [new Agent/UDP]

$ns attach-agent $n(0) $udp0

# Create a CBR traffic source and attach it to udp0

$cbr0 set packetSize_ 500

$cbr0 set interval_ 0.005

$cbr0 attach-agent $udp0

#Create a Null agent (a traffic sink) and attach it to node n(3)

set null0 [new Agent/Null]

$ns attach-agent $n(3) $null0

#Connect the traffic source with the traffic sink

$ns connect $udp0 $null0

#Schedule events for the CBR agent and the network dynamics

$ns at 0.5 "$cbr0 start"

$ns rtmodel-at 1.0 down $n(1) $n(2)

$ns rtmodel-at 2.0 up $n(1) $n(2)

$ns at 4.5 "$cbr0 stop"

#Call the finish procedure after 5 seconds of simulation time

$ns at 5.0 "finish"

#Run the simulation

$ns run
