71 Interference Cancellation for Throughput Gain in Wireless Networks Mojtaba Khalili m khalili@ec iut ac ir Date of Submission 2014 01 11 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan IranDegree M Sc Language PersianSupervisor Naghmeh Sadat Moayedian moayedian@cc iut ac irAdvisor Faramarz Hendessi hendessi@cc iut ac irAbstractIn the recent years by the growth of wireless networks and extra demands for the multi mediatraffic requires designing techniques that can increase the network throughput and use thenetwork capacity efficiently is required Techniques which uses packet interference in thephysical layer are suitable candidates for designing such interference aware techniques in higherlayers In this thesis cross layer design in combination with SIC and SPC techniques is considered SIC isa helpful technique for multi packets reception in wireless networks SPC is also a way to send multiplepackets from a transmitter The use of SIC and SPC increases the throughput and reduces end to enddelay in wireless networks In this study the SIC and SPC in a joint formulation of scheduling routingand flow control is used Hence a graph model should be used that considers the impact of the SIC andSPC in interference model and also allows a node to send and receive at the same time Moreover ascheduling algorithm based on the physical interference model which uses the SIC and SPC isconsidered In the rest of this study to increase the throughput of wireless networks networkcoding is combined with SIC and SPC The simulation results show that using this techniquescan increase the system throughput generally and also in some certain cases increase the networkthroughput even twice Keywords Multihop Wireless Networks successive interference cancellation superposition coding NetworkCoding Link Scheduling
