Dear Profesor;

I am on my PhD study.

And I wanna ask you some questions if it is possible.

generally about network routing algorithms and their some variations on OMNeT++.

What questions?

About algorithms or about routing protocols?

I wanna learn how to implement different routing algorithms on omnet such as bellman ford?

How can we use Kruskal, Prim algorithms for tree network topolojies?

What about modeling different routers? For example is it possible to use cisco router 8000 series?

Rip implements Belmand Ford. You can use these protocol.

Tree routing algorithms aren’t implemented because no specific multicast protocol is implemented.

You can change the configuration of the router (time processing and similar, number of ports, etc ) but not specific router is implemented.

What about flow situations ? Can we use ford fulkerson and floyd warshall algoritms for flow problems in network?

And is there any possible way on studying spanning tree algorithms on omnet?

Thank you so much for your quick and useful answers.

The maximization of flows aren’t implemented. They aren’t used by any of the actual routing protocols used by IETF, at least that I know.

RPL, OLSR, OSPF, DSR : Dijkstra,

RIP,AODV, DYMO : Belmand-Ford.

MPLS with QoS needs source routing that is Dijkstra.

Dear Alfonzo;

I got an error when studying on rip/SimpleTest.

I have added 3 more routers and did the connections.

But I could not understand. Can you help me please?

Probably you have modified the node model and included other lookback interface. The nodes can only have one lookback interface.

Dear serap bakioglu

I am also on my PhD study and am doing research in wsn. Can you please help me in simulating a simple wsn with a simple routing algorithm.

I need a start at this stage dear...
