Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...

In this paper we review position-based routing for wireless ad hoc and for wired networks. This form of routing assumes that nodes are aware of i) their own position; ii) the position of their neighbors (obtained through the exchange of beacon messages); and iii) the position of the node that is the intended destination of the packet.

Position-based routing protocols have become increasingly popular in mobile ad-hoc networks because they can use geographical node position information to route data packets to their destinations. Each node periodically sends its geographical position information to its neighbours by using beacon packets. Data packet routing in position-based routing protocols uses the neighbours’ position info...

Position-based routing protocols have become more popular in Mobile Ad hoc network (MANET) due to their advantages in using geographical position information of the nodes to route the data packet to the destination node. Each node periodically sends their geographical position information to its neighbors using beacon packets. Data packet routing in position-based routing protocol uses neighbor...
