Analysis the MAC Protocol of IEEE 802.11 Wireless LAN

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. The architecture of the IEEE 802.11 WLAN is designed to support a network where most decision making is distributed to the mobile striation. The first, IEEE Standard 802.11a, is an orthogonal frequency domain multiplexing (OFDM) radio in the UNII bands, delivering up to 54 Mbps data rates. The second, IEEE Standard 802.11b is an extension to the DSSS PHY in the 2.4 GHz band, delivering up to 11 Mbps data rates. In this Project study the main emphasis has been given to the MAC layer of the Wireless LAN IEEE 802.11 MAC Protocol. Also the physical layer of the Wireless LAN IEEE 802.11 MAC Protocol has been described. The implementation of the Wireless IEEE 802.11 MAC Protocol is observed through a simulation.
