Creating a attack simulation

I'm gonna create a honeypot for cars. There will be a couple of honeypots for preventing DDOS attacks, An wireless AP and a few more internal networks in a vehicle. The thing is to create a simulation of a network like in a vehicle. Also, if it possible, i need the before and after effects of honeypots. It could be done NS3 or GNS3

I need a simple simulation for a in-vehicle network

and an attack simulation results as a reference to how attacks affect the car's internal network.

simple simulation followed by an attack simulation for DDoS, replay attacks and some malware-based attack results? you could use any topology. but it should be formed like a in-vehicle network.
