ABSTRACT
Vehicular Communication Networks (VCNs) provide a promising technology for improving traffic safety and traffic efficiency in different road systems. Based on DSRC/WAVE Technology VCNs offer an efficient communication platform for Intelligent Transportation Systems (ITS) and related ITS services as well as value-added services such as multimedia and data services. However, different types of services have different requirements of network performance. The rapidly varying network topology in access network, where vehicles may travel with high speeds of more than 200 Km/h, creates several challenges for QoS provision and efficient routing integration. To investigate possible solutions for those challenges, related issues have to be addressed in conjunction with VANETs and roadside networks. Consequently, relevant solutions are developed for QoS mechanisms and routing protocols for both VANETs and roadside networks. This chapter introduces some of those most important solutions and proposes an overview of future ITS service, called “Start-to-Destination Driving Route Reservation (S2D-DRR).” Finally, some open research issues will briefly be introduced with an objective to spark new research interests in the field of VCNs.
