I am designing a routing protocol for SDN-FANET, what could be the best simulator that enables ad hoc communication between UAV and centralized openflow communication between UAVs and the sdn controller ? Thank you
NS-2 development stopped more than 10 years ago. I would suggest you try NetSim (www.tetcos.com) - Edu users can get a a free evaluation.
When selecting a simulator for your SDN-FANET routing protocol design, consider factors such as the level of detail required, ease of use, community support, and compatibility with existing simulation models and tools. Additionally, verify that the simulator provides the necessary features for modeling both ad-hoc communication between UAVs and centralized OpenFlow communication between UAVs and the SDN controller.
NS-3 (Network Simulator-3)
OMNeT++
Mininet
QualNet
These simulators offer the necessary features for simulating ad hoc communication between UAVs and centralized OpenFlow communication between UAVs and SDN controllers.
