Vehicular Ad-hoc NETworks (VANETs) have become viable and valuable for their wide variety of novel applications, such as safety of road, content sharing of multimedia, commerce on wheels, etc, using advanced wireless technologies. Distribution of multi-hop information in VANETs is constrained by the high mobility of vehicles and the frequent disconnections. Geographic routing do not require route maintenance and route construction phases hence they are widely adopted for VANETs. With connectivity awareness, they perform well in terms of reliable delivery. Flooding is use in some protocols to obtain destination position.
