Study of Computer Network Issues and Improvising Drop Rate of TCP Packet Using NS-2

TL;DR

This paper investigates network security issues and analyzes TCP packet drop rates in a simulated 5-node wired network using NS-2, aiming to improve understanding of network performance under different conditions.

Contribution

It presents a simulation-based analysis of TCP packet drop rates in a small network, exploring the effects of varying rate parameters on network performance.

Findings

Packet drop rate varies with rate parameter changes.

Graphical analysis shows performance differences under different conditions.

Simulation results help in understanding TCP behavior in small networks.

Abstract

As the enormous use of internet increases day by day so as security concern is also raise day by day over the internet. In this paper we discuss the network security and its related threats and also study the types of protocols and few issues related to protocols in computer networks. We also simulate the design of 5 node wired network scenario, its packet drop rate analysis through TCP protocol using NS2 as a simulator. Analyzed the performance of 5-node network when the packet is drop down by graphical method also called as Xgraph when rate parameter is in mb and also analyzed the performance of same network by changing the value of rate parameter at same time so no packets would drop down at same time and also analyzed the performance by Xgraph method.
