I have N nodes in a simulated network. All nodes n (1<= n <=N) are randomly positioned in XY plane. Every node n has it's own Xn and Yn.

I need to model connections among all nodes. Connection is simple - just a link between nodes.

But... not all nodes are connected to all other nodes. Because each node has a limited Wireless signal range, each node can establish connection with some neighbor nodes, but not with all of them. This depends on distance between nodes.

My idea is: Before doing a simulation, I'd run init procedure. This init proc would randomly fix all Xn and Yn. Then would calculate distances from node n to all other nodes and enable connections between node n and all other nodes within Wireless signal range. All other connections would be disabled.

My question is:

How can I implement all this connections among nodes in Simulink with Simevents? And how can I enable or disable them? Any idea of any better approach?
