Vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications have raised a series of challenges due to data security and user privacy. Vehicular ad hoc networks (VANETs) have become the target of malicious attacks. Authentication has been widely adopted in VANETs to guarantee secure communications. However, existing authentication schemes have failed to meet stringent time requirements of...
In this paper, we study the clustering problem for crossroads in Vehicular Ad hoc Networks (VANETs). Considering the load balancing of both the whole network and each cluster based on the multiple metrics, an Enhanced Low Overhead and Stable Clustering (EnLOSC) scheme is presented to ensure the stability and security of clusters and to reduce the communication overhead in this case. The proposed capability...
Vehicular ad hoc networks (VANETs) are regarded as essential ways for vehicles to share information with each other. As communication range is limited, multiple relay nodes are often required for establishing the multi-hop routing path between the source node and the destination node. Dependability of such routing path may be compromised due to different motion states of vehicles. In this paper, we...
The framework of RFID systems on Roads (RSR) was recently proposed to improve the driving safety and the drivers' comfortability. In RSR, RFID readers are installed on vehicles, and passive RFID tags are deployed on each lane. The tags store the lane level road information, which will be provided to the vehicles when they are passing by the tags. As the RFID tags are passive and have to be programmed/updated...
