Performance of Distributed Medium Access Control with an Enhanced Physical-Link Layer Interface

A distributed MAC algorithm is presented to support an enhanced physical-link layer interface with multiple transmission options at each link layer user. Theoretical performance analysis is provided and is shown to match well with the simulated results. Example is given to demonstrate significant throughput improvement of the distributed MAC algorithm compared with the classical 802.11 distributed coordination function (DCF), due to the support of multi-packet reception.
