Performance Analysis of AODV Protocol with TCP/FTP Traffic and Improved AODV Protocol with UDP/CBR Traffic for Optimizing Routing and QoSin MANET

Amandeep Kaur, Kuldeep Singh


The transmission and reception of information between sourceand destination in a MANET relies on the performance of the traffic scenario (application traffic agent and data traffic) used in a mobile ad-hoc network. The traffic scenario basically defines the reliability and capability of information transmission, which formulates its performance analysis. The objective of this paper is to compare the performance of TCP/FTP on Normal AODV and UDP/CBR traffic on Improved AODV routing protocol generally implemented in a mobile ad hoc environment. An empirical study has been done using NS-2. Exhaustive simulations have been done to analyze the results, which are evaluated for performance metrics, such as throughput, packet delivery ratio and average end to end delay. The effect of variations in, number of nodes, on the network performance is analyzed over a wide range of their values. It is observed that the UDP/CBR on IMPROVED AODV offers a far better performance for throughput than TCP/FTP on Normal AODV; in case of PDR, it offers great PDR for CBR traffic on Improved AODV than TCP on NORMAL AODV.The results follow these trends over a wide range of simulation parameters.
