The ns-3 CSMA/CD model is helpful for simulating Ethernet or wired LANs. In ns-3, the CSMA/CD protocol is simulated for accessing a shared medium and detecting collisions. It is implemented by the ns-3 scheduler by giving access to nodes based on the First Come First Served (FCFS) principle. In a CSMA/CD network simulation, collisions are detected using a global shared variable among nodes and it also simulates random exponential backoff by nodes to retry their transmission during...
