Performance simulation of MANET protocols with the combination of horizontal and vertical topology using NS2

A MANET (Mobile Ad Hoc Network) can support large as well as small scale network topology. Based upon our specific small scale MANET requirement, we have taken the combination of horizontal and vertical topology with less number of nodes to check how the various MANET protocols like pro-active (DSDV) and re-active (AODV and DSR) performs in this manner. In this research study, we have observed these MANET protocols on the basis of various performance metrics like Packet Delivery Ratio, Average End to End Delay and No of Packets Dropped. Finally in this research study, we observed that DSDV protocol performs better in less number of nodes in the combination of horizontal and vertical topology. Simulations of this research study performed in NS2 (i.e. Network Simulator Version 2.34)
