Performance Analysis of a Hybrid Efficient and Reliable MAC Scheme for Vehicular Ad Hoc Networks in Safety Applications

Safety applications are the highest priority services in the Vehicular Ad Hoc NETworks (VANETs). To support the highest priority service, the Medium Access Control (MAC) protocol is designed to provide efficient broadcast. Compared to IEEE 1609.4, a new multi-channel MAC for VANET (HER-MAC) is proposed which is more reliable in safety applications. In this paper, we propose an analytical model ...

Hybrid vehicular communications based on V2V-V2I protocol switching

In this paper, a hybrid communication paradigm for vehicular networking is presented in which connectivity is provided by both existing network infrastructure (e.g., wireless network access points) through a vehicle-to-infrastructure protocol and traditional vehicle-to-vehicle networking. Preexisting infrastructure can provide seamless connectivity, especially when vehicles are sparse or travel...

An Integrated Services MAC Protocol For Local Wireless Communications - Vehicular Technology, IEEE Transactions on

This paper proposes a medium-access control (MAC) protocol for integrated voice/data services in local wireless communications. The proposed protocol is a hybrid of R-Aloha and Aloha reservation adapted to local wireless environment. In the proposed hybrid Aloha-reservation/R-Aloha (HAR) protocol, data messages are transmitted using Aloha-reservation protocol, whereas voice packets are transmit...

Security Architecture for Vehicular Communications

Despite recent progress for vehicular communication in research, development, field tests, and standardization, security is still in an early phase though it represents a crucial part of the vehicular communication system. So far, no vehicular security architecture has been proposed which integrates existing individual solutions for vehicle registration, data integrity, authentication, and so o...
