ANALYSIS OF TCP ALGORITHMS IN THE RELIABLE IEEE 802 . 11 b LINK

IEEE 802.11b technology networks have become increasingly common and an increasing number of devices are communicating with each other over lossy links. Unfortunately, TCP performs poorly over lossy links as it is unable to differentiate the loss due to packet corruption from that due to congestion. This paper presents systematic analysis and modeling results of TCP Reno, Vegas and Veno algorithms in the IEEE 802.11b networks link. In this work the following questions are analyzed: principles of operations, and the throughput dependence on random loss and long links delays, that emerge as using from MAC layer reliable protocols. The aim of the presented modeling is to sift features of TCP protocol algorithms and find its dependence on throughput in the IEEE 802.11 networks.
