WIMAX NETWORK SIMULATOR OMNET++ PROJECTS

  WIMAX NETWORK SIMULATOR OMNET++ PROJECTS is one of our dedicated services, started with the initiatives of renowned researchers and dedicated professionals. We have accomplished nearly 1000+ Wi-max Network Omnet++ projects for students and scholars from various parts of the world. It is an open source simulation framework implemented in C++. Also it offers Modular support (in C++) for development, which is one of the significant reasons for its widespread usage. Omnet++ has a separate Module support [NUMBAT] for the simulation of Wimax-Networks. Scholars can opt Omnet for the simulation of Wi-max Networks to get proficient and effective result.

We have nearly 100+ skilled developers and network engineers, working for student’s career upliftment and academic excellence. If you wish to enhance your academic performance and grades with the help of our guidance, approach us today. We will offer you an all round project guidance with 24/7 support.

WIMAX-SIMULATION IN OMNET++:
  • Omnet++ is an extensible, component based C++ Simulation library and framework used for network simulation
  • Simulation of Wi-max Network is performed in Omnet++ using NUMBAT Model.

Simulation Steps for Wimax Simulation:
  • Create the compound modules using NED and/or GNED


network physim extends Physim

{

parameters:

}

network physim extends from Physim

  • Configure the chosen Physim compound modules

module Physim

{

parameters:

int LogLevel; //was volatile double

int numBS; //volatile double

int numSS; //volatile double

@display(“bgb=0,0”);

submodules:

BS[numBS]: BS {

parameters:

@display(“p=100,200,r,200;i=device/antennatower_l”);

gates:

in[numSS];

out[numSS];

}

SS[numSS]: SS {

parameters:

@display(“p=50,50,r,50;i=device/pc_s”);

}

CN[numSS]: CorrNode {

parameters:

@display(“i=device/pc2;p=50,355,r,50”);

}

internet: Internet {

parameters:

@display(“p=480,280;i=misc/cloud”);

}

connections allowunconnected:

for i=1..numSS {

CN[i-1].ipOut –> internet.ipIn++;

internet.ipOut++ –> CN[i-1].ipIn;

}

for i=0..numBS-1 {

BS[i].networkOut –> internet.ipIn++;

internet.ipOut++ –> BS[i].networkIn;

}

}

  • Save this file as Physim.ned
  • Declare class(e.g WMaxCtrlSS.{cc.h})derived from FSM class and list of states in header[.h] file

WMaxCtrlSS: WMaxCtrlSS {

parameters:

@display(“i=block/cogwheel,#ce1821;p=264,80”);   }

typedef enum {//To define list of states

STATE_OPERATIONAL, // normal operation

STATE_WAIT_BSHO_RSP, // wait for BSHO-RSP message

STATE_SEND_HO_IND, // send HO-IND message

Run the simulation and also perform performance analysis using the following metrics:

  • Measure-time since also last received data
  • Measure number of dropped packets[also no routing/address configured]
  • Measure time since last transmitted data
  • Handover time
  • Throughput and also Jitter

 We also have provide an overview about WIMAX NETWORK SIMULATOR OMNET++ PROJECTS for students to get an idea about Wimax Network Simulator Omnet++ projects. NUMBAT is also a Module framework used for Wimax simulation in Omnet++. We also have provided a brief explanation about NUMBAT along with the overall simulation steps involve also in Wimax simulation. To avail our service further, approach us through also our online guidance service. We are also there to serve you at 24/7.
