Understanding the Challenges of VANETs
VANETs which stand for Vehicular Ad-Hoc Networks is a subset of mobile ad-hoc networks (MANETs) which is specifically designed for communication among vehicles and roadside units (RSUs) and They can play a lead role in improving road safety, traffic efficiency, and providing comfort to both drivers as well as passengers despite of so many benefits VANETs also has to face several challenges which including:
- Dynamic topology: The network topology constantly changes as vehicles enter and leave the network.
- Limited resources: Vehicles have limited processing power and storage.
- Security vulnerabilities: they are susceptible to a various kind of security attacks.
SDN for Vehicular Ad-Hoc Networks (VANETs)
In recent years there is a rapid evolution in vehicular communication systems which has been a crucial point in the advancement of intelligent transportation systems (ITS) Among these Vehicular Ad-Hoc Networks (VANETs) have emerged as an important component facilitating vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication However, managing the dynamic nature of VANETs poses significant challenges inviting Software-Defined Networking (SDN) to arrive as a promising solution to enhance the performance and efficiency of VANETs.
