Performance Evaluation of VeMAC Supporting Safety Applications in Vehicular Networks

Performance Evaluation for DSRC Vehicular Safety Communication

In this paper, an analytic model is proposed for performance evaluation of vehicular safety related services in dedicated short range communications (DSRC) system on highway. The generation and service of safety messages in each vehicle is modeled by an M/G/1 queue. But since vehicles share a medium, the service time distribution of a message needs to take contention and backoff into account. W...

Performance analysis of DSRC priority mechanism for road safety applications in vehicular networks

Dedicated short range communications (DSRC) has been regarded as one of the most promising technologies to provide a robust medium and affordable enough to be built into every vehicle. It is designed to support both road safety and commercial applications. Road safety applications will require reliable and timely wireless communications. However, as the medium access control (MAC) layer of DSRC...

Efficient Routing for Safety Applications in Vehicular Networks

Vehicular Networks: A Survey on Architecture, Communication Technologies and Applications

The Intelligent Transportation System (ITS) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. This system consists of many fixed and mobile nodes (Vehicles, Trains, Vessels, Air planes), Wireless and Wired Telecommunication Technologies to exchange information between mobile nodes or betwee...

End-to-end performance in vehicular networks with an emphasis on safety and security applications

In wireless networks, the presence of interference among wireless links introduces dependencies among flows that do not share a single link or node. As a result, when designing a resource allocation scheme, be it a medium access scheduler or a flow rate controller, one needs to consider the interdependence among nodes within interference range of each other. Specifically, control plane informat...
