Simulation of Sockets in Network Simulator

306 views Asked by At

I want to simulate some nodes with Network Simulator(NS-3). The communication between them is UDP traditional socket. i want to know, for simulation is it enough to simulate from Transport Layer till Application Layer or is needed also to simulate Physical and Data-Link Layer of OSI Layers?

NS3 is complete OSI layer simulation from Application Layer to Physical Layer. Thus, you need specify on what kind of network component that is your simulation run. It can be a very simple setup to do that using NS3 helpers API.

Here is a very simple UDP simulation example on NS3 : https://www.nsnam.org/docs/doxygen/first_8cc_source.html
