Project Title:  Performance Analysis of Wi-Fi using ns-2

Abstract

Wireless Fidelity (Wi-Fi) is widely used for wireless communication and is based on IEEE (Institute of Electrical and Electronics Engineers) 802.11 standard. Wi-Fi allows multiple users to transmit data from one place to another using high frequency radio waves. Nowadays, many devices such as smartphones, laptops, tablets and other wireless devices can be connected through a single wireless (Wi-Fi) Network. Also, Quality of Service (QoS) is a major factor to support a number of applications that use the Wi-Fi network, so in this regard QoS parameters need to be analyzed for a better performance. The main purpose of this project is to compute and analyze the QoS parameters of Wi-Fi network such as throughput, packet loss rate, end-to-end delay, and jitter during Voice over Internet Protocol (VoIP) using network simulator 2 (ns-2). In this project, we initiated voice calls and group chats between multiple users along with the movement of one of the user during the voice call. The results obtained demonstrate that Wi-Fi provides better performance and QoS for small area networks.
