NS2 WIRELESS PROGRAM

       NS2 Wireless Program is an initiative start by world renown experts for the budding students, who search for external aid for NS-2 code support. We offer complete code support in NS-2 for students, who want to work in complex and advanced topics. Also, We have focus on Wireless networks as majority of networking applications are developed today using wireless technology. Majority of students prefer to work with Wireless-Networks today, as an initiative to further support them we have started our guidance support. Our well traine developers and experts are always available in Online, to support you with your needed code in NS-2. Approach our experts and upgrade your grades.

NS-2 WIRELESS-PROGRAM

     NS2 Wireless Program offers you complete code support for the accomplishment of your project/research, assignments or lab cycles. NS2 simulation can be used for both wired and wireless networking. We have emphasize here on Wireless-Network as it is one of the major need of the budding scholars. To work with Ns2, you must have knowledge of trace files, Nam files, Xgraph, AWK script, TCL and C++. If you want to learn all these concepts along with a project, approach our online tutoring service.

Below, we also have provide complete information about how to configure a node in NS-2. You may think that why we have focused on this minute concept. It may look minute but knowing about is must to code in NS-2. Once you will understand it, you can work on any code on your own. If you need any particular program in NS-2, approach us, we will offer you best code for your need.

Major Node Components in Wireless Simulation:

CHANNEL TYPE:

  • It is used to indicate the channel type i.e. wired or wireless network


        set val(chan)  Channel/WirelessChannel

RADIO PROPAGATION MODEL:
  • Used to predict the received signal power of each packet
  • Each wireless node maintains a receiving threshold at the physical layer. If it receives any packet below that threshold, it marks it as error and drops it.

 set val(prop)   Propagation/TwoRayGround

MEDIUM ACCESS CONTROL PROTOCOL[MAC PROTOCOL]
  • Used to send and receive packets by sending request to the nodes.

  set val(mac)  Mac/802_11

ROUTING PROTOCOL:
  • Plays a significant role in Networking as data transmission between nodes is based on the packet route and employed routing protocol
  • There are numerous Routing protocols available, here we have taken Ad hoc On demand vector Routing protocol:

set val(rp)  AODV

INTERFACE QUEUE:
  • Used in packet transmission, it stamps on each transmitted packet with meta data [contains information like transmission power, wavelength etc]
  • This meta data in the packet header is used by the propagation model to determine whether the packet has minimum power to receive.

set val(ifq) Queue/DropTail/PriQueue

TRAFFIC MODEL:
  • Based on CBR[Constant Bit Rate] or VBR[Variable bit Rate]
  • Below we have given example syntax using CBR with TCP

   set val(traffic)        cbr

   set val(traffic)        tcp

ANTENNA TYPE:
  • For wireless Networks, Omni antenna can be used

   set val(ant)  Antenna/OmniAntenna

         Based on the above mentioned parameters, we can construct Wireless network in NS2. To better understand about it, let’s have a sample code explanation.

Sample code for node configuration:

$nssim node-config

set val(chan)   Channel/WirelessChannel \#”Channel Type”

setval(prop)   Propagation/TwoRayGround\#”Radio- Propagation Model”

set val(ant)    Antenna/OmniAntenna \#”Antenna Type”

setval(ll)     LL \#”Link Layer”

set val(ifq)    Queue/DropTail/PriQueue\#”interference Queue”

setval(ifqlen) 50 \#”Max packet in ifq”

set val(netif)  Phy/WirelessPhy \#”Network Interface type”

setval(mac)    Mac/802_11 \#”MAC Protocol”

set val(rp)     MAODV \#”Routing Protocol”

setval(nn)     51 \#”Nodes”

set val(x)      700 \#”X dimension of Simulation Area”

setval(y)      700 \#”Y dimension of Simulation Area”

set val(stop)   5 \#”Simulation Time”

setval(traffic)cbr \#”Traffic Model”

set val(traffic)tcp \#”Traffic Model”

      Once you are done with Node configuration, you can create the nodes and topology as per your application requirement. This is the fundamental of NS2-simulation, which we have emphasized in this article to give some basic information to students. You can refer our other articles in this for more information about NS-2. We have focused on such basic information for students, as we prefer students to learn from the basics. If you are done with these basics, you can approach us online for more advanced information about NS-2. We will tutor you in such a way that you will be able to develop your own code for your projects, assignments or lab cycles. Need our guidance, then approach us soon.
