Evaluation of various routing protocols in VANET - Manish Sharma - Bog

In VANET high speed is the real characteristics which leads to frequent breakdown,interference etc. Moreover the energy consumption of the mobile terminals is increasing rapidly due to higher CPU clock speeds and inclusion of more Programs such as gaming, Internet, credit functions etc. Therefore Performance of ad hoc routing protocols is helpful to improve the Quality of Service (QOS) at higher altitude. In this work we studied various Adhoc routing protocols Reactive, Proactive & Hybrid, taking in to consideration parameters like speed, altitude, mobility etc in real VANET scenario at an altitude of 1500m. The Chosen protocols are AODV and DYMO (Reactive), OLSR (Proactive) and ZRP (hybrid) and are compared for various battery models along with above the Protocols are also compared for IEEE 802.11(MAC), IEEE 802.11(DCF), IP, FIFO and throughput standards along with using Qualnet as Simulation tool. Energy Conservation and good Quality of Service (QoS) is the prime concern.Since IEEE 802.1, covers both physical and data link layer. Hence performance of the protocols in these layers helps to make a right selection.In all parameters Proactive protocols OLSR and Fisheye outperforms.
