AODV routing protocol modification with dqueue(dqAODV) for VANET in city scenarios

Vehicular ad hoc network (VANET) is considered as a sub-set of mobile ad hoc network (MANET). It provides smart Transport System i.e., wireless ad-hoc communication in between vehicles and vehicle to roadside equipments. Based on this technology road network is classified into two types 1. vehicle to vehicle interaction, 2. vehicle to infrastructure interaction. The objective of VANET is to provide safe, secure and automated traffic system. For this automated traffic technique several types of routing protocols have been developed. But routing protocols of MANET are not directly applicable to VANET. In this study, we proposed a modified AODV routing protocol in the context of VANET with the help of dqueue introduction into the RREQ header in the C++ code of built-in AODV protocol in NCTUns-6.0 simulator. Recently Saha et al [1] has reported the results showing the nature of modified AODV obtained from the rudimentary version of their simulation code. It is mainly based on packed delivery throughput. It shows greater In-throughput information of packet transmission compare to original AODV. It has been observed from the study that our protocols needs less overhead and yield greater performance in compared to conventional AODV.
