The interaction between communication entities, which is unique in the network setting, have been at the root of many difficult challenges in communications and information theory. This monograph advocates a sequential approach to make progress on the network communication problem. In order to do this, the channel (and source) model to capture the essence of the network communication problem are simplified and connected to the original problem. This leads to the concept of approximate characterizations of the channel capacity region and source coding rate regions. Approximate solutions to...

In multi-hop wireless networks; that is, networks where messages must traverse multiple nodes before reaching their destination, wireless relay nodes must play a dual role: they serve as intermediate steps for relaying schemes and as part of the mechanism that allows interference management schemes. Hence, relaying and interference management are two key aspects of communication in wireless networks. Both these aspects are introduced in a tutorial manner before going on to consider the combination of the two. In multi-hop multi-flow networks, the challenge is to combine the insights obtained...
