routing protocol

Please does anyone can help me, I need to simulate a mobile network in Matlab (nodes + links) and possibly the search for the shortest path between source node and destination node

Answer 1

[Walter Roberson]

Dijkstra's Algorithm is appropriate for searching for the shortest path between nodes.

You should be considering, however, that the shortest path between nodes is not necessarily the path that will be most reliable or have the clearest or fastest transmissions, as the shortest path might happen to involve nodes that are very busy or even overloaded.

Mr. Walter, i'm doing research in network routing, too. can you help me how to build computer network simulation in matlab??

maybe you can give me tutorial or some step to build it..

thank you..

@Walter: I think that if it's possible to have a snapshot of the entire network at any point in the simulation, you can factor the load and bandwidth of each node into the cost function for the search algorithm.

@Firmansyah wahyu: That's a bit like saying "I'm a researcher but I don't understand my subject". Make sure you understand what you are trying to achieve - if you don't, then there's no way you can write code to achieve it. Learn how to write code in MatLab if you haven't already. Then if you are having problems, ask a SPECIFIC question like "I have a bunch of nodes representing routers in a graph with the following connections and properties (insert list): can anybody suggest a good way to represent these in MatLab?".

Hi,

I have invented a new routing protocol. Can I implement it in MATLAB?

It is to forward the packets from source to sidtenation.

please contact me at: [e-mail]

Thanks

[Walter Roberson]

It can probably be programmed in MATLAB; MATLAB is a general purpose programming language.

Generally speaking, though, it can be easier to model routing protocols in Simscape.

Many thanks Mr. Walter,

Any idea where to find resources to learn this tool?

Regards

Abdullah
