Successive Interference Cancellation (SIC) is an effective way of multi-packet reception to combat interference in wireless networks. The authors focus on link scheduling in wireless networks with SIC, and propose a layered protocol model and a layered physical model to characterize the impact of SIC. In both the interference models, they show that several existing scheduling schemes achieve the same order of approximation ratios, independent of whether or not SIC is available. Moreover, the capacity order in a network with SIC is the same as that without SIC. They, then examine the impact of SIC from first principles.
