  Successive interference cancellation (SIC) is a physical layer technique that
enables the decoders to decode multiple simultaneously transmitted signals. The
complicated model of SIC requires careful design of the MAC protocol and
accurate adjustment of transmission parameters. We propose a new MAC protocol,
known as CSMA-SIC, that employs the multi-packet reception capability of SIC.
The proposed protocol adjusts the transmission probabilities to achieve
throughput optimality.
