In this project, multi-access channel (MAC) protocol based on distributed auction algorithm where each link runs distributive in order to maximize the accumulated sum of QoS. The algorithm is based on a carrier sensing multiple access (CSMA) implementation of the distributed auction algorithm. It does not require any exchange of information between users. Users need only to observe a single channel at a time and sense if there is a transmission on that channel, without decoding the transmissions or identifying the transmitting users. We compare the performance of the proposed algorithm with the state-of-the-art scheme using simulations of realistic long term evolution (LTE) channels. It is noted that the algorithm exploits the CSMA mechanism to bypass the need for an auctioneer and by doing that, implements the auction algorithm distributive. For this purpose, links compute a continuous back-off time that is decreasing with their bit. The highest bit for a particular channel is simply the first link which accesses this channel. However, in contrast we assume all links can sense the channel that they choose, and all links will agree on which link is the highest bidder for their channel.

- In proposed system, the main objective of the algorithm is based on a carrier sensing multiple access (CSMA) implementation of the distributed auction algorithm. It does not require any exchange of information between users. Users need only to observe a single channel at a time and sense if there is a transmission on that channel, without decoding the transmissions or identifying the transmitting users.
- The millimeter-wave supports wide bandwidth, and the short wavelength of it enables the miniaturization of antennas. Therefore, millimeter-wave based mobile communication systems can be equipped with more antennas in the same space as long-term evolution (LTE) base stations. However, short wavelengths can cause high path loss and low signal to noise radio (SNR).
