Relayed transmissions enable low-power communications among nodes (possibly
separated by a large distance) in wireless networks. Since the capacity of general relay …

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 …

We consider transmission of packets in two-hop wireless ad hoc networks in which relay
nodes are deployed between the source-destination pairs. Based on results from extreme …

Although the wireless relay transmission has been recognized as one of the effective
approaches in extending the coverage area and improving the network capacity, the delay …

The buffer-aided wireless relay technology is widely used in the 4G and the 5G wireless
systems. This technology has advantages of throughput enhancement and coverage …

In this paper, we study the bandwidth efficiency (throughput) and the energy efficiency of
relay networks considering both the physical layer and the medium access control (MAC) …

For delay-limited communication over block-fading channels, the difference between the
ergodic capacity and the maximum achievable expected rate for coding over a finite number …

In the interference-limited communication scenarios, the interference impairs the data
transmission and further degrades the delay performance. In this letter, the stochastic delay …

In this paper, we consider a wireless network consisting of a source node, a destination
node and multiple relay nodes under Rayleigh fading. Cooperative diversity in the network …

This work investigates the multiple-input multiple-output system in the context of the
selective decode-and-forward multihop relay network under short-packet communications to …
