Mobility Prediction in Vehicular Ad Hoc Networks: A Survey

Abstract

VANET is an ad-hoc network that organizes itself and is composed of self-regulating nodes
where the vibrant node mobility changes the network topologies frequently. The important goal of
introducing VANET stands to upgrade road safety conditions to minimize extent of road mishaps. The
nodes are very mobile in vehicular ad hoc network so routing becomes complex job. As the VANET
nodes move very fast the topology changes accordingly. So node mobility prediction in an ad-hoc
network of vehicles remains a very important issue. Further prediction of mobility helps to estimate
the stable path between the nodes which leads to better routing. Estimating secure paths among the
routing of nodes reform in a better way, thereby reducing the overhead and minimizing interruptions
in connections. This paper explores VANET's basic architecture and discusses a number of current
mobility prediction techniques, and concludes with summary of VANET's proposed mobility
prediction methods.
