Abstract

The objective of this paper is to measure and compare the performance of TCP/FTPand UDP/CBR traffic in wired networks and also to understand the relationship between network density and throughput in wireless networks. Study has been done using NS-2 and AWK scripts. Exhaustive simulations have been done to analyze results, which are evaluated for performance metric, namely throughput, link throughput. And pack delivery ratio. The effect of variations in link bandwidth, number of nodes on the network performance is analyzed over a wide range of their values. Results are shown in terms of graphs and tables.

Keywords : wired, wireless,TCP, UDP, NS-2, AWK, agent, performance metrics, throughput, packet delivery ratio, and link bandwidth.
