Abstract

As all can see that the demand of WLAN is increasing gradually, so here it is necessary to improve the performance of WLAN. There are many parameters which can directly affect the performance of WLAN like data rate, modulation scheme, buffer size, RTS threshold etc. One of them is fragmentation threshold. In this paper we are rising up the performance of WLAN by moderating the value of fragmentation threshold using OPNET as a simulation tool. By using fragmentation threshold parameter the large packets are be fragmented into smaller packets. Furthermore it can be demonstrated that by increasing the value of fragmentation threshold the throughput and load of the WLAN is increased, it also decreased the delay and media access delay of WLAN. This increased throughput and load simply implies that the performance of WLAN is enhanced. By increasing fragmentation threshold value we can also decreases the probability of discarding packets.
