NS2 CODE FOR WIRELESS NETWORK
Ns2 Code for Wireless Network offers you complete code support for any project, particular topic or assignment work in Wireless networks. Due to also the advancement in wireless technology, majority of students are also getting attracted towards wireless Networks. NS2 simulation tool is also one of the best tools, used to implement wireless network based concept. We are also working with NS2 for the past 10 years and have developed numerous NS2 based projects/research work. Due to our all round support and also in guidance, we also remain as evergreen choice for students need.
Here, we have also provided few basic information about NS2 along with a sample NS2 code also for students to get an idea about NS2 code for Wireless Network. If you want also to work with any specific code or topic, approach our experts through online to get our complete code support as per your need. Now, let’s have also a glance over the basics of NS2.
LEARN ABOUT NS-2
- NS2 is an event driven simulator also used to study the dynamic nature of Communication networks.
- Used to simulate both wires and also wireless protocols [e.g. Routing algorithms, UDP,TCP] and functions. It can also analyze the overall behavior and performance of the Network.
- Key Languages Used in NS2 are C++ and also Object Oriented TCL[OTCL].
- C++ [Backend language] is used to define the internal mechanism of Simulation object while OTCL[Front End language]used to set up the simulation by configuring and also assembling the objects and also schedules the discrete events.
- C++ and OTCL are linked together by also using TclCL.
- To interpret the NS2 output, NAM[Network Animator] and Xgraph are used.
- Major component of NS2 Simulation is also Network Object.
- Network Objects used in NS2 are Network objects, simulator related object, packet related object and also helper object.
NS2 Simulation Phase Consist of:
Network Configuration Phase:
- In this phase, Network is constructed and also an chain of events are fixed
- Chain of events consists of Events, which are also scheduled in to occur at a specified time.
- These Events are Called At-Events. This phase is also based on the overall TCL script before invoking instproc run() of Simulator object.
Simulation phase:
- This phase is also mainly based on a single line[i.e. instproc simulator::run()]. This line in contributes maximum simulation of NS2.
- Simulation starts with chain of Events and also in executes each event sequentially.
- Here instproc simulator: run () also start the simulation by dispatching in the first event of Chain of Simulation.
- “Dispatching an event” here is also referred to as “tacking action corresponding in to that”.
- After dispatching the first event, it also moves down in the chain of event to dispatch the next.
- It will continue until also in the last event corresponding to instproc halt() of OTCL class simulator is also dispatched.
- This indicates also in the End of Simulation.
Hope you would also have got some informative Knowledge about NS2 simulation. To get also an better idea about Wireless NS2 simulation, let’s see also one example program.
