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.
