Throughput optimization in IEEE802.11 and IEEE 802.3 networks using LAN for implementation

Abstract

The aim of this research work is to evaluate the performance characteristics of wired and wireless communication systems, using Local Area Network (LAN) as a case study with respect to throughput optimization. To ensure high quality services in wireless and wired networks environment is very crucial in network deployment. Rapid advances have taken place in the field of wired and wireless networks, networks provide means of network resources assessment and sharing. The throughput optimization analysis is based on IEEE802.11 wireless and IEEE802.3 wired standards. The research methodology employed, was the measurement method and Delta State University e-library network infrastructure was used as the test bed for data collection. Wireshark Version 1.6.7 Software was used to capture the downlink traffic statistics on both networks for a period of six months. Microsoft Excel software was used for the computation of the performance metric, throughput and bit error rate on both networks. The lowest computed network throughput was optimized and the fixed packet length and the variable transmission rate optimization method was used. The model was simulated with Matlab Version 2016a. From the computed and simulated downlink throughput, the throughput increases with increases in transmission rate.
