Abstract :

This research paper used an adaptive queuing model to determine an optimum acceptable retransmission limit of Wireless Campus Area Network which gave minimum packet loss rate. Data traffic was collected from the network using “Winbox” software monitoring tool for a period of 11 months from 31th January 2011 to 30th December 2012. The average arrival rate of 176.5 kilobits per second, average service rate of 746 kilobits per second and packet error rate of 0.76 were obtained. Like most researchers a buffer space of 50 was used in the analysis and graphs were plotted using Excel Spreadsheet. The optimum retransmission limit was found to be 10, which gave a minimum packet loss rate of 0.05. Above and below 10 retransmissions resulted in more packet loss.
