摘要
Nodes in VANETs move at high speed. This high mobility makes most conventional routing protocols incompatible with this type of network. A new class of geographic routings has emerged. Most of these routing protocols suppose that the nodes position is known in advance and that the nodes do not have time to move significantly between sending packets and receiving their acknowledgments. This assumption is not always realistic because of the high nodes movement and the low wireless transmissions range. Consequently, packets routing may fail if this assumption is not guaranteed. In this paper, we propose a prediction mechanism, which will estimate the expected new vehicle position to reduce the packet loss.
