. Information Technology and Computer Science, 2014, 03, 20-29 Published Online February 2014 in MECS ( refers to a network has a range of about 10–100 meters to 10 Km collision resolution mechanism used in random access per machine, depending on the emission power, the data MAC protocols. This algorithm is used in Ethernet rate, the frequency, and the type of antenna used. Many (IEEE ) wired LANs. In Ethernet networks, this different models of antenna can be employed: omnis algorithm is commonly used to schedule (omni-directional antennas), sector antennas (directional retransmissions after collisions. antennas), yagis, parabolic dishes, or waveguides The paper’s goal is to minimize the time transmission (cantennas). The other type of transmission support is cycle of the information between mobiles moving in a the infrared. Infrared rays cannot penetrate opaque Wi-Fi by changing the BEB algorithm. The Protocol materials and have a smaller rang
