While Mininet was initially explored for VANET simulations, it's not ideal for current research due to a few limitations:
Focus on SDN: Mininet excels at simulating Software Defined Networks (SDN) with OpenFlow switches. VANETs typically don't rely on SDN, making it less relevant.
Development Halt: The core development of Mininet stopped in February 2021. There might be limited support for newer technologies used in VANETs.
Here are some better options for VANET simulations:
SUMO (Simulation of Urban Mobility): This popular tool focuses on traffic simulation and can be extended to model VANET communication.
NetSim: This software specifically caters to simulating network communication, including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) interactions crucial for VANETs.
These alternatives offer more features and active development for simulating VANET behavior.
