Successive Interference Cancellation (SIC) is an effective way of multi-packet reception to combat interference. As conventional CSMA (Carrier Sense Multiple Access) is designed for single packet reception, it is unclear whether or not CSMA performs well to exploit the SIC capability. In this paper, the authors analyze the performance of a simple CSMA protocol in a network with SIC. For a given link, they derive the residing areas of an interfering node when simultaneous transmission is allowed and when the interference is harmful, respectively. They show that, though SIC provides many new transmission opportunities, CSMA cannot effectively exploit them.
