This paper proposes a new model for wireless relay networks referred to as “1-2-1 network”,
where two nodes can communicate only if they point “beams” at each other, otherwise no …

This paper studies networks that consist of N half-duplex relays assisting the communication
between a source and a destination. In ISIT'12 Brahma et al. conjectured that in Gaussian …

Usually, wireless radios are half-duplex, ie they can not transmit and receive at the same
time over the same frequency band. However, building on self-interference cancellation …

The problem of operating a Gaussian Half-Duplex (HD) relay network optimally is
challenging due to the exponential number of listen/transmit network states that need to be …

In this paper, we study a simple question: when are dynamic relaying strategies essential in
optimizing the diversity-multiplexing tradeoff (DMT) in half-duplex wireless relay networks …

This paper considers a single-source single-destination half-duplex-relay network with
arbitrary topology, where the source communicates with the destination through a direct link …

This paper studies the 1-2-1 half-duplex network model, where two half-duplex nodes can
communicate only if they point" beams" at each other; otherwise, no signal can be …

This paper explores the network simplification problem in the context of Gaussian half-
duplex diamond networks. Specifically, given an N-relay diamond network, this problem …

This paper investigates the problem of how to efficiently operate Gaussian half-duplex
diamond networks with N relays. It derives sufficient conditions that ensure that the network …

In ISIT2012 Brahma, Özgür and Fragouli conjectured that in a half-duplex diamond relay
network (a Gaussian noise network without a direct source-destination link and with N non …
