                                 ABSTRACT 
                                  

                                 Over the past few years, wireless communications have become more and more popular. 
One example is mobile phones. Fifty years ago, if you want it to talk with you friends in California, you have to
sit next to a telephone. That is not anymore. Nowadays, you can talk with your friends while you are driving. The 
same thing is true for computer communications. Wireless telephony has been successful because it enables 
people to connect with each other regardless of location. This new technology targeted computer networking, 
and now the Internet connectivity is implemented successfully by wireless networking technology. The most 
successful one is the  802.11 wireless LANs.  

                                 In 1997, the IEEE adopted the IEEE 802.11 standard which is used for wireless computer 
communications. The IEEE 802.11 defines two layers. The first layer is the Physical layer (PHY) which specifies
the modulation scheme used and signaling characteristics for the transmission through radio frequencies. The 
second layer is the media access control (MAC). This layer determines how the medium is used. In this project,
we will not talk about the PHY layer; instead we will focus on the MAC layer.
