Performance evaluation of Various Ad hoc routing protocols in IP, throughput and FIFO using Qualnet in hilly Terrains for VANET

VANET in hilly terrains suffers frequent signal breakdown, interferences and other hinderances, affecting QoS (Quality of service). In this paper various Ad hoc routing protocols are compared for IP, Throughput and FIFO taking in to consideration various parameters of real traffic scenarios like altitude, nodes, speed, data size & weather mobility model using Qualnet as a simulation tool at higher altitude of 1970m. Since network layers covers IP, Throughput and FIFO, hence comparison of various Ad hoc routing protocols like AODV and DYMO (Reactive), OLSR (Proactive) and ZRP (hybrid) taking IP, Throughput and FIFO as comparison parameters helps to make right selection of protocols to improve QoS in hilly terrains. Varying parameters of VANET shows that in the real traffic scenarios proactive protocol performs more efficiently
