Description:
Number of nodes (22) is fixed in the program. Nodes are configured with specific parameters of a mobile wireless node. After creating the nam file and trace file, we set up topography object. set node_ ($i) [$ns node] is used to create the nodes. Initial location of the nodes is fixed. Specific X, Y coordinates are assigned to every node. Nodes are given mobility with fixed speed and fixed destination location. Here we set the initial size for the every node by using initial_node_pos. AODV routing protocol is used here. $val(stop) specifies the end time of the simulation. UDP agent is attached to sender node. LossMonitor agent is attached to receiver node. Both the agents are connected and CBR traffic is attached to UDP agent. Now communication set up for nodes are established.
