Static routing is very simple. Each node has a routing table where each entry has the destination and the next node. On receiving a packet, a node find the entry corresponding to the packet s destination, and forwards it to the next node. If there is no entry, the node drops the packet. That s it.

While writing the static routing protocol in ns2 is easy, we have to set a routing tables at every node. This can be done by writing an external program. For example, when you generate a topology, you can set up routing table with the shortest path metric.

Source codes

In this project, we are going to write new source codes (static_routing_pkt.h, static_routing.h, and static_routing.cc) and new scr ipt (static.tcl), and modify existing codes (packet.h, queue.cc, ns-lib.tcl, ns-mobilenode.tcl, and ns-packet.tcl)

The source codes of this project is available here.
