The emergence of vehicular ad-Hoc Network (VANET) through Inter-Vehicle Communications (IVC) has promised countles applications that could greatly improve the safety of drivers,ease traffic control and enhance the overall driving experience in the near future.Successful implementations of VANET would require standardizerd network protocols,secure communications platforms,reasonable coverage of wireles network among vehicles as well as cooperation from driver themeselves.In the networking domain,routing protocols that can cope the unique characteristic of a VANET environtment is a subject of interest for many.This paper reviews routing protocols that have been adapted for VANET,particurarly using the position-based routing method.it gives an overview of the developments of the routing protocols for VANET environtment,and compares them in the context of a driver's safety and driving experience.
