“…Hadaller et al [12] showed that since the wireless conditions, including MSs mobility pattern, of a vehicular environment is predictable, and then the vehicular opportunistic access can be greatly improved when exploiting this information in the vehicular environment. In previous work [9] [10] we have focussed on WLAN-based roadside backbone networks. We presented a multi-layer proxy system and accordingly discussed a feed-forward mechanism, which predicts the future vehicle position using a determined vehicle velocity as a key parameter for the estimation of the time a client spends within the WLAN cell and thus the volume of data can be transmitted to that cell.…”

“…Due to the high-speeds have to be supported in vehicular communication networks (VCNs) the most developed solutions for network-related prefetching/preloading are initiated in conjunction with vehicular environments, as to see by Krohn et al [9] [10] as well as Ott and Kutcher [11] concerning cells and islands use cases, respectively. Hadaller et al [12] showed that since the wireless conditions, including MSs mobility pattern, of a vehicular environment is predictable, and then the vehicular opportunistic access can be greatly improved when exploiting this information in the vehicular environment.…”

Wireless Mesh Backbones (WMBs) provide promising solutions for future networking strategies. Due to the mesh nature and thus the resource restrictions of such backbones the integration of mobility aware preloading mechanisms is essential for QoS provisioning, especially in environments with high mobility clients. This paper presents a novel concept, called Mobility-aware Forwarding in Advance (MAFIA), to enhance the QoS provided by WMBs. Accordingly, two mechanisms are developed: best effort and QoS-oriented MAFIA. Best effort MAFIA mechanism provides preloading mechanism regardless of QoS requirements. QoS-oriented MAFIA considers traffic prioritization in conjunction with flows and their requirements. Both MAFIA mechanisms are used in a WMB developed as a roadside backbone network for vehicular environments.

Vehicular communication networks (VCNs) have emerged as a key technology for next-generation wireless networking. DSRC/WAVE as a leading technology for VCN provides a platform for Intelligent Transportation System (ITS) services, as well as multimedia and data services. Some of these services such as active safety and multimedia services have special requirements for QoS provision. However, when providing QoS, the VCN characteristics are the cause for several new issues and challenges, especially when vehicles travel at high speeds of up to 200 km/h. These issues are addressed in the context of roadside networks and vehicular ad hoc (unplanned) networks (VANETs), including vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications. Accordingly, plenty of solutions for provisioning QoS in VCNs have been classified in regards to VANETs and roadside networks, on the one hand, and to layer-2 and layer-3, on the other hand. Consequently, several QoS solutions, including medium access and routing protocols, are presented and discussed. Additionally, open research issues are discussed, with an objective to spark new research interests in the presented field.
