Abstract : 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. Further in case of regions like sparse and void regions, upraise hop count by
frequent use of the recovery strategy. Some geographic routing protocols adopt the minimum weighted algorithm depending
on distance or connectivity to select intermediate intersections. However, the path with higher connectivity or the shortest path
may include numerous intermediate intersections. Therefore, these protocols yield routing paths with higher hop count. In this
paper, we propose a distance based greedy routing and hop greedy routing scheme that yields a routing path with the minimum
number of intermediate intersection nodes while taking connectivity into consideration. Moreover, back-bone nodes are
introduced that play a key role in providing connectivity status around an intersection. Also the back-bone nodes allow packet
to be forwarded in the changed direction by tracking the movement of source as well as destination. Distance based greedy
routing overcomes the limitations of a Hop Greedy Routing algorithms. In this paper we have considered design and
implementation of routing algorithms that will provide maximum packet delivery ratio and minimum end to end delay.
