Burst Error Analysis Introduced in Multiple Traffic of Protocols TCP Reno, Cubic, Westwood and Vegas on a Model of Hybrid Topology

Abstract

This paper explores the behavior shown by the protocols TCP Reno, Cubic, Vegas and Westwood in presence of errors in bursts occurred in multiple traffic over a hybrid topology. The development is based on the analysis of case studies, where it starts with a mixed topology of two wired and two wireless nodes, with two flows of the same variant of the TCP protocol, subsequently increasing the number of nodes until reaching 8 wired nodes behaving as senders and 8 wireless nodes as receivers. In all cases only one of these flows suffers a burst error and through the tests we analyze how the flow recovers from the burst. For this study, behavioral tests were carried out using the NS-2 network simulator, on a hybrid topology (wired and wireless), also incorporating burst errors of different lengths, typical of wireless links.
