In recent years, the IEEE 802.11 Wireless Local Area Network (WLAN) has been widely deployed in Indoor wireless Communication and it includes detailed specification of both medium access control and physical layer. The most research area of these two layers is Medium Access Control (MAC) layer in the first sub layer of data link layer. To access the medium from physical layer using MAC layer will be coordinating the random access of the medium. In wireless LAN MAC protocols is to coordinate the access of wireless client station in shared medium using Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) protocol for MAC layer.
