Is it possible to simulate a network architecture/model in matlab?

Hello, I want to simulate a network communication model (you can say its 3 tier model), where a node A wants to send a request to B and vice versa, there could be multiple conditions for example:

A --direct (involve heavy processing)--> B   % if near
A --> (Server (local)) --> B % if far
A --> (Server (local)) --> (Server (Main)) --> (Server (local)) --> B % if very far

I want to simulate these three conditions and compare the throughput and latency. Please if anyone can suggest which toobox is appropriate for that purpose? or any simulation example like that already exist!

A lot depends on what layers you want to simulate.

In the bit you describe, SimEvents is perhaps appropriate -- but it is not what would be used if you need to simulate waveforms and channel interference for 5G or 802.11an for example.

No physical layer, I may need an discrete event like simulation.

Then SimEvents would seem most likely.

Thank you for your response dear Walter Roberson, I was looking at how a communication network can be simulated on SimEvents (components like; Node, Router, Connections with bandwidth, Messages/Packets) but unable to find any suitable help on that, can you please suggest me to find some hands-on guide or any tutorial for that? I am very beginner in matlab, your help will be really appreciated. thank you..
