Evaluation of Proactive, Reactive and Hybrid Ad Hoc Routing Protocol for IEEE 802.11 MAC and 802.11 DCF in VANET Using QUALNET
In VANET high speed is the real characteristic which leads to frequent breakdown, interference etc. Therefore Performance of adhoc routing protocols is helpful to improve the Quality of Service (QOS). In this paper, the authors studied various adhoc routing protocols, Reactive, Proactive & Hybrid, taking in to consideration parameters like speed, altitude, mobility etc in real VANET scenario. The AODV and DYMO (Reactive), OLSR (Proactive) and ZRP (hybrid) protocols are compared for IEEE 802.11(MAC) and IEEE 802.11(DCF) standard using Qualnet as a Simulation tool.
