Effects of mobility on stability in vehicular ad hoc networks

This paper focuses on the characterization of vehicle mobility in vehicular ad hoc networks (VANETs). The performance of vehicle mobility in terms of link available time and the number of inter-vehicle link changes for maintaining active links in VANET is analyzed using both the handover and random moving models. The theoretical analysis is verified by simulation experiments. The numerical results indicate that the vehicle random moving analytical model is able to provide a more accurate description of the complicated vehicle moving behavior than the conventional random way point mobility model, especially when vehicles are moving relatively fast.
