| dc.description.abstract | Traditionally, interference in wireless networks is considered a destructive phenomenon and treated as random noise. If multiple packets are transmitted simultaneously on the same channel, the assumption is that these packets collide and therefore all of the overlapping packets need to be retransmitted. As a consequence, to reduce interference, MAC protocols are typically designed to schedule a single transmission at a time on a channel. In contrast, modern decoding techniques such as successive interference cancellation (SIC) and physical-layer network coding (PNC) aim to extract information from overlapping signals by exploiting the additive nature of electromagnetic waves. The resulting structure at the physical layer transforms interference into a potential advantage. Higher-layer protocols, however, need to be redesigned to make optimal use of this structure. The goal of this thesis is to develop new higher-layer protocols or adapt existing protocols to optimally use the advanced decoding techniques available at the physical layer. Special focus is on the MAC layer. The main body of the thesis is about designing protocols over a SIC-capable physical layer, but in one of the chapters, it is assumed that the physical layer is also capable of doing PNC. The effect of SIC over several types of networks, namely, networks with centralized scheduling with certain goals (such as maximum throughput scheduling and proportional fair scheduling), random access (i.e., ALOHA like) networks and networks with linear coding capability are studied. | en_US |
