Evaluating the Effect of Transmission Range (TX) on the Performance of DSDV, AODV and DSR in Vehicular Ad hoc Network (VANET) Traffic Scenarios

Vehicular Ad-hoc Networks (VANETs) is an emerging technology that derives from the well-established Mobile Adhoc Network (MANET). VANETs could face a great challenge arising from the dynamic nature of the nodes which occurs due to the frequent change in network topology. In a wireless network, Transmission Range (TX) is an essential part of successful packet delivery. In addition, TX affects network performance by changing the antenna height. If the transmission range is minimized or maximized, that consequently has effects on the network performance such as throughput, packet delivery ratio, the end to end delay and routing load. In this work, various scenarios have constructed to evaluate the effect of transmission range on DSDV, AODV and DSR routing protocol in a VANET highway design using Network Simulator (NS-2).
