Descr iption:

This network consists of 3 nodes. After creating the nam file and trace file, we set up topography object. Set node_ ($i) [$ns node] is used to create the nodes. Here we set the initial position for the every node by using initial_node_pos. After that $Val (stop) is used to tell to nodes when the simulation ends. the nodes have Tcp connection. A "tcp" agent is attached to Client1, and a connection is established to a tcp "sink" agent attached to node0 and node1. As default, the maximum size of a packet that a "tcp" agent can generate is 1KByte. A tcp "sink" agent generates and sends ACK packets to the sender (tcp agent) and frees the received packets. The ftp is set to start at 10.0 sec and stop at 150.0 sec. Here we were using DSR routing protocol.
