A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum), and usually providing a connection through an access point to the wider internet. Therefore, it is very important to improve their signal to noise performance. In this paper, our main aim is to enhance the WLAN metrics using buffer size optimization. We demonstrate that WLAN performance can be improved by tuning parameters such as buffer size, fragmentation threshold and request to send (RTS) thresholds Through OPNET simulation. In this paper we emphasize on buffer size parameter. Customizing this parameter opposes to using the values specified in the standards will reduce delays, throughput and reduce load on nodes. Finally the results are compiled to improve the performance of wireless local area networks.
