Comparative Study of Different Types of Queues in Go-Back-2 Networks in NS2

Abstract
Different types of queues can be used to analyse the performance of any topology. Here go-back-2 networks are used with different queues such as DropTail, FQ, and SFQ. Queue limit is varied and analysis is carried out to evaluate their performance. The Network Simulator [NS2] is used for performance study and drawing the analysis. The Simulation results are evaluated in different buffering capacities using topology of Go-back-2 networks keeping in mind the effect of buffer size. For each type of queue the number of dropping packets and the number of receiving packets are found using a software called trace graph. Trace graph can be used to plot the simulation time vs the number of receiving or dropping packets. Keywords - Go-Back-2 networks, Queues, NS2, Trace graph.
