NW LAB - NS2 PROGRAMS - ALGORITHMIMPLEMENTATION OF UNICAST ROUTING PROTOCOL
AIM: To implement Unicast Routing protocol using network simulator (ns-2).
ALGORITHM1. Define new simulator2. Define different colors for data flows (for NAM)3. Define a new Trace file and open it4. Define a new NAM Trace file and open it5. Define a 'finish' procedure – to flush trace record in the `trace and trace output
files.6. Define the routing protocol as Distance Vector (DV)7. Create six nodes – n0,n1,..n58. Create links between the nodes with 0.3Mb and 10 ms Link with DropTail option9. Give node position (for NAM) to place six nodes in the layout10.Setup a TCP connection – attach TCP Source Agent to node n0 and TCP sink
agent to node n511.Setup a FTP over TCP connection12.Define configuration such that link between nodes n1 and n4 to be failed at 1.0
interval, and up again at 4.5 interval13.Start the simulation
