Effect of number of nodes and speed of nodes on performance of DSDV, AODV, AOMDV, DSR and GPSR routing protocols in VANET

A Vehicular Ad-hoc Network (VANET) is considered as an advanced network mechanism of wireless vehicle nodes. By dynamic changeable topologies and symmetric links of network, high challenges van be evaluated by VANET protocols. The vehicles can send effective information of traffic and road status. Proper and appreciating routing mechanism is necessary for the configuration of nodes in VANET. Many network simulators have intrinsic features to characterize it from others. To make communication within the network with different routing protocols, the most ordinary simulator tool is NS 2.34. In this research work, three types of routing protocols namely on demand routing protocol (AODV, AOMDV, DSR), proactive routing protocol (DSDV) and geographical routing protocol (GPSR) have been experimented by altering values of number of nodes and speed of the nodes. Different performance metrics namely average end to end delay, average throughput, normalized routing load, packet delivery ratio have been successfully implemented for comparison purpose. Choosing effective routing protocol on specific scenario is the crucial focus on this research work.
