Interference Cancellation and Scheduling in Wireless Networks

SIC (Successive Interference Cancellation) is an effective way of multiple packet reception (MPR) to fight with interference in wireless networks. Most of the existing methods for SIC in wireless networks are mainly focusing on link scheduling. For characterizing the impact of SIC, two interference models such as layered protocol model and layered physical model are introduced. Various existing scheduling schemes are examined for their performance in a network with SIC. To explain the generic behavior of the scheduling schemes, the capacity of a network with SIC is to be analyzed. The scheduling performance investigates two scenarios such as chain and cell topology. In chain topology, the average throughput values are compared with SIC and without SIC. In cell topology, the normalized throughput is compared with number of receiver nodes with different node density. The performance of proposed scheme has been verified using network simulator to show that the approach is efficient.
