Abstract
ABSTRACT Several MAC protocols proposed for IEEE 802. 11 wireless local area network. In that research, authors used the same backoff scheme proposed in the IEEE 802. 11 i. e. the minimum contention window size is 32. However we can vary the minimum contention window size as per the network requirement. It the network size is big we can take big contention window and when the network size is small we can take small window size. This way we can increase the performance of network and decrease the average delay. In this paper we analyze the performance of IEEE 802. 11 wireless ad hoc network, in terms of varying the minimum contention window and simulate to validate our numerical result in OPNET 14. 5.
