In Vehicular ad hoc network (VANET) the implementation and testing of the performance of routing protocols (www.ietf.org/rfc/rfc3561.txt, www.ietf. org/rfc/rfc4728.txt [1], Boppana et al. in An adaptive distance vector routing algorithm for mobile, ad hoc networks. INFOCOM 2001. IEEE Xplore, vol. 3, pp. 1753-1762, (2001) [2]) are very costly and difficult in real life situation. With the help of Network Simulators the Real-life situation can only be mimicked. Out of many simulators as available at present the NTCUns-6 (Wang et al. in Comput Netw 42(2):175-197, 2003 [3]) is much more versatile due to its inherent features. Most of the well known routing protocols are available for simulation procedure. But, it is found that, AODV is implemented in NCTUns in such a manner that it broadcast the route request within the same network, but multicast the route request between two different networks. Hence it seems a unnecessary wastage of Route Request (RREQ) (www.ietf.org/rfc/rfc3561.txt, www.ietf.org/rfc/rfc4728.txt [1]) packet for its neighbour networks (close network). To cope the problem the ADOV routing protocol has been modified accordingly within the simulator keeping other protocols unaltered. In suitable simulation scenario AODV routing protocol broadcast RREQ packets among the nodes of different networks functioning in the different lanes of the road and we got an enchantment in throughput for our modified AODV (m-AODV). © Springer India 2015.
