The Research of Vehicular Cloud Computing (VCC)

- VCC is an emerging research field that leverages the resources of vehicles, such as their computing, storage, and communication capabilities, to create a cloud-like infrastructure.
- This dynamic and mobile cloud can provide various services to vehicles and their passengers, including traffic management, infotainment, and safety-critical applications.
- Key research areas in VCC include dynamic resource allocation, mobility management, cloud recontruction, and efficient communication protocols.
- Researchers are exploring how to effectively manage the dynamic and unpredictable nature of VCC environments, ensuring reliable and secure services.
Research on V2V Precaching in Content-Centric Vehicular Networks (CCVN)

- CCVN shifts the communication paradigm from location-based addressing to content-based retrieval, which is inherently suited for the high mobility of vehicles.
- V2V precaching is a proactive strategy that stores popular data in the local caches of neighboring vehicles before an explicit request is made, effectively turning vehicles into mobile data hubs.
- Current research focuses on developing sophisticated mobility prediction and content popularity models to determine the optimal timing and location for data placement.
- This approach significantly minimizes content delivery latency and reduces the signaling overhead on the core network by utilizing the short-range communication of moving nodes.
- Modern studies increasingly leverage Machine Learning (ML) and cooperative caching schemes to handle the unpredictable topology and intermittent connectivity of the vehicular environment
Research on V2I Precaching in Content-Centric Vehicular Networks (CCVNs)

- CCVNs proactively stores popular content at Roadside Units (RSUs) or edge servers based on content names to facilitate faster retrieval.
- This strategy aims to significantly reduce content delivery latency and backhaul pressure by predicting vehicle trajectories and pre-positioning data before a vehicle enters a specific RSU’s coverage area.
- Research focuses on optimizing cache replacement policies and developing high-accuracy mobility prediction models to effectively manage the intermittent connectivity of high-speed vehicles.
- Recent studies leverage Deep Reinforcement Learning (DRL) to dynamically allocate cache resources, balancing the trade-off between storage costs and user Quality of Service (QoS).
Research on Multimedia Data Delivery in UAV-based Vehicular Networks

- UAV-based Vehicular Networks utilize Unmanned Aerial Vehicles as flexible, high-altitude relays or edge servers to provide the high-bandwidth connectivity required for bandwidth-intensive multimedia traffic.
- Research primarily focuses on joint trajectory optimization and resource allocation to maintain a stable Quality of Experience (QoE) for high-definition video streaming amidst high mobility.
- Sophisticated interference management and beamforming techniques are being developed to mitigate signal fluctuations caused by the dynamic movement of both aerial and ground nodes.
- Furthermore, current studies integrate AI-driven predictive modeling to proactively adjust to channel conditions, ensuring seamless and low-latency data delivery in complex urban environments.
