Challenges of SDN for VANETs
While integrating SDN into VANETs offers substantial benefits, it also comes with some set of challenges:
- Standardization: There is currently no standard for SDN in VANETs.
- Privacy concerns: The centralized structure of SDN gives rise to apprehensions regarding data privacy and highlighting the need for robust measures to safeguard sensitive information.
- Reliability: The SDN controller must be highly reliable to avoid network outages.
in order To address these challenges, researchers are now exploring various approaches One among such approach is to deploy multiple SDN controller by distributing geographically to ensure uninterrupted control over the network and Another solution motivate use of edge computing where computing resources are placed closer to where data is generated and thereby will reduce latency and improve the response time.
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.
