1. Creating a simulated network with tow nodes.

Step 1: First I created a folder by the name lab_1 in samples folder.

Step 2: There after I created a file by the name tictoc1.ned .As shown bellow.

simple Txc1{

gates:input in;output out;

}

//// Two instances (tic and toc) of Txc1 connected both ways.

// Tic and toc will pass messages to one another.//

network Tictoc1{

submodules:tic: Txc1;toc: Txc1;

connections:tic.out --> { delay = 100ms; } --> toc.in;tic.in


3/41

void Txc1::initialize()

{

if (strcmp("tic", getName()) == 0){

// create and send first message on gate "out". "tictocMsg" is an// arbitrary string which will be the name of the message object.cMessage *msg = new cMessage("tictocMsg");send(msg, "out");

}

}

void Txc1::handleMessage(cMessage *msg){

send(msg, "out");}

Step 4: Creating another file by the name omnetpp.ini.

[General]

# nothing here

[Config Tictoc1]

network = Tictoc1

Step 5: I wrote following commands which screen shorts have show bellow.

1. cd samples/lab_1

2. opp_makemake -f

3. make

2. Enhancing two does with Tic Toc



simple Txc2{

parameters:@display("i=block/routing"); // add a default icon


}

network Tictoc2{

submodules:

tic: Txc2 {parameters:

@display("i=,green"); // do not change the icon (first arg of i=) just colorize it}toc: Txc2 {

parameters:@display("i=,gold"); // here too

}connections:

tic.out --> { delay = 100ms; } --> toc.in;tic.in

// The `ev' object works like `cout' in C++.EV getName() is name of the msg object, here it will be "tictocMsg".EV

int counter; // Note the counter here

};

Define_Module(Txc3);

void Txc3::initialize(){

WATCH(counter);

4. Adding Parameters



simple Txc4{

parameters:bool sendMsgOnInit = default(false); // whether the module should send out a

message on initializationint limit = default(2); // another parameter with a default value@display("i=block/routing");

gates:input in;

output out;}

//// Adding module parameters.//network Tictoc4{

submodules:tic: Txc4 {

parameters:

sendMsgOnInit = true;@display("i=,cyan");

}toc: Txc4 {

parameters:sendMsgOnInit = false;@display("i=,gold");

}connections:



17/41

Step 3: Then in the same way I created another file by the name txc4.cc .As showing bellow.

class Txc4 : public cSimpleModule{

private:int counter;


};



// Initialize the counter with the "limit" module parameter, declared// in the NED file (tictoc4.ned).

counter = par("limit");

// we no longer depend on the name of the module to decide// whether to send an initial messageif (par("sendMsgOnInit").boolValue() == true){

5. Using Inheritance

Its implementation doesnt exist in the document

6. Modeling Processing Delay



simple Txc6{

parameters:@display("i=block/routing");


}

network Tictoc6{

submodules:tic: Txc6 {

parameters:@display("i=,green");

}toc: Txc6 {

parameters:@display("i=,blue");

}

connections:tic.out --> { delay = 100ms; } --> toc.in;tic.in


22/41


// Initialize the counter with the "limit" module parameter, declared// in the NED file (tictoc4.ned).counter = par("limit");

// we no longer depend on the name of the module to decide// whether to send an initial messageif (par("sendMsgOnInit").boolValue() == true){

EV

Step 5: The Final output is:

7. Random number and parameters



simple Tic8{



}


24/41

simple Toc8{

parameters:@display("i=block/process");

gates:

input in;output out;}

network Tictoc8{

submodules:tic: Tic8 {

parameters:@display("i=,cyan");

}

toc: Toc8 {parameters:@display("i=,gold");

}connections:



25/41

virtual void handleMessage(cMessage *msg);};


Txc7::Txc7()

{event = tictocMsg = NULL;

}

Txc7::~Txc7(){

cancelAndDelete(event);delete tictocMsg;

}


event = new cMessage("event");tictocMsg = NULL;

8. Timeout, cancelling timer



simple Tic8{


gates:input in;

output out;}

simple Toc8{

parameters:@display("i=block/process");


}

network Tictoc8{

submodules:tic: Tic8 {

parameters:@display("i=,cyan");

}toc: Toc8 {

parameters:@display("i=,gold");

}connections:



28/41


#include #include #include

class Tic8 : public cSimpleModule{

private:simtime_t timeout; // timeoutcMessage *timeoutEvent; // holds pointer to the timeout self-message

public:Tic8();virtual ~Tic8();


};Define_Module(Tic8);Tic8::Tic8(){

timeoutEvent = NULL;}Tic8::~Tic8(){

cancelAndDelete(timeoutEvent);}void Tic8::initialize(){

// Initialize variables.

timeout = 1.0;timeoutEvent = new cMessage("timeoutEvent");

// Generate and send initial message.EV


29/41

else // message arrived{

// Acknowledgement received -- delete the stored message and cancel// the timeout event.EV

10. Created a simulated network with six nodes.

Step 1: First I created a folder by the name lab_sixnode in samples folder.


simple Txc10{


gates:input in[]; // declare in[] and out[] to be vector gatesoutput out[];

}

network Tictoc10{

submodules:tic[6]: Txc10;

connections:tic[0].out++ --> { delay = 100ms; } --> tic[1].in++;tic[0].in++ tic[2].in++;tic[1].in++ tic[4].in++;tic[1].in++ tic[4].in++;tic[3].in++ tic[5].in++;tic[4].in++


32/41


protected:virtual void forwardMessage(cMessage *msg);virtual void initialize();virtual void handleMessage(cMessage *msg);

};



if (getIndex()==0){

// Boot the process scheduling the initial message as a self-message.char msgname[20];sprintf(msgname, "tic-%d", getIndex());cMessage *msg = new cMessage(msgname);

scheduleAt(0.0, msg);}

}


if (getIndex()==3){

// Message arrived.EV

11. Channels and inner type definitions

Step 1: First I created a folder by the name lab_inner in samples folder.

gates:input in[]; // declare in[] and out[] to be vector gatesoutput out[];

}

//// Using local channel type definition to reduce the redundancy// of connection definitions.//network Tictoc11

// Message arrived.EV

12. Using two ways connections

Step 1: First I created a folder by the name lab_con in samples folder.


simple Txc12{


gates:inout gate[]; // declare two way connections

}

// using two way connections to further simplify the network definitionnetwork Tictoc12{

types:channel Channel extends ned.DelayChannel {

delay = 100ms;}

submodules:tic[6]: Txc12;

connections:tic[0].gate++ Channel tic[1].gate++;

tic[1].gate++ Channel tic[2].gate++;tic[1].gate++ Channel tic[4].gate++;tic[3].gate++ Channel tic[4].gate++;tic[4].gate++ Channel tic[5].gate++;
