Authors: Onaifo F, Jaiyesinmi D, Oyedeji AO, Ezekiel SO
A faster and reliable method of sending and receiving information is very important in the globalized world today. Therefore, electronic copies of file and messages are rapidly replacing hard paper information. As a result, the rate of upload and download becomes very important when electronic messages are sent or received. This paper studies the end-to-end delay in a wireless local area network. End to end delay is the summation of processing, transmission, propagation and queuing delay which is the upload or download time when copying a file. This work studies the various delays that accompany the download of various file sizes. In this study, computers are networked together using Ubiquiti radio with one dedicated computer serving as a server. File sizes ranging from 5 MB to 1000 MB were downloaded to determine the download time. The effect of varying processor speed on a given file size download was investigated. The results show that download time varies and depend on processor speed, the number of processes or sessions and wireless speed. The distance of the computer from the router was independent of the download time.
