Abstract

Vehicular Ad hoc Networks (VANET) is a new technology that has recently evolved and is widely finding applications on areas such as road traffic, payment collection, tourist guiding information and natural hazards. The main goal of VANET is to provide safety and comfort to passengers.VANET is also an Ad hoc network, the protocols used in Mobile ad hoc network suits VANET. The ad hoc routing protocols can be categorized as Reactive protocols and Proactive protocols. This paper presents architecture for VANET and considers Ad hoc On Demand Distance Vector (AODV) from reactive routing group and Destination Sequenced Distance Vector (DSDV) from Proactive routing protocol. These protocols were simulated using NS-2 package and were compared in terms of packet delivery ratio, end to end delay and number of dropped packets in two scenarios: by varying the maximum number of connections and varying the speed of the mobile node with different number of connections.
