Mobile Network Simulator NS3

Mobile Network Simulator NS3 – What is Mobile Network?How to Implement Mobile Network Simulator ? Sample Source Code for Mobile Network simulator.

Ns-3 is not a backwards-compatible extension of ns-2; Mobile Network Simulator NS3 is a new simulator. The two simulators are both written in C++ but ns-3 is a new simulator that does not support the ns-2 APIs.

Basics of Mobile Network Simulator:

The simulation time moves in discrete jumps from event to event.
Simulation::Run() gets it all started.
A simulation scheduler orders the event execution.
C++ functions schedule events to occur at specific simulation times.
Simulation stops at specific time or when events end.

Sample code for setting ipv4 configuration in Mobile Network Simulator:

Ipv4InterfaceContainer csmaInterfaces;
Ipv4InterfaceContainer wifiInterfaces;
InternetStackHelper internet;
internet.Install (NodeContainer::GetGlobal ());
Ipv4AddressHelper ipv4;
ipv4.SetBase (“10.1.1.0”, “255.255.255.0”);
csmaInterfaces = ipv4.Assign (csmaDevices);
ipv4.SetBase (“10.1.2.0”, “255.255.255.0”);
wifiInterfaces = ipv4.Assign (wifiDevices);
