Random coding, along with various standard tech-niques such as coded time-sharing, rate-
splitting, superposition coding, and binning, are traditionally used in obtaining achievable …

In this paper, we aim at characterizing the gain induced by using relay channels in a linear
network under both capacity constraint and realistic energy model. We express a general …

Wireless communication links suffer from outage events caused by fading and interference.
To facilitate a tractable analysis of network communication throughput and latency, we …

We present a deterministic channel model which captures several key features of multiuser
wireless communication. We consider a model for a wireless network with nodes connected …

Multihop channels are believed to provide benefits in performance because the reduction in
transmission distance per hop directly translates to increased channel gains. However, a …

We determine the asymptotic capacity of a Gaussian multiple-relay channel as the number
of relays tends to infinity. The upper bound is an application of the cut-set theorem, and the …

Real-time and energy-efficient transmissions are two critical demands for status update
systems, however it is difficult to meet these requirements simultaneously. This paper …

Two-way relaying promises considerable improvements on spectral efficiency in wireless
relay networks. While most existing works focus on physical layer approaches to exploit its …

A wireless network with fading and a single source-destination pair is considered. The
information reaches the destination via multiple hops through a sequence of layers of single …

The impact of multi-hopping schemes on the communication latency in a relay channel is
studied. The main aim is to characterize conditions under which such schemes decrease the …
