In this work, we present a successive opportunistic relaying protocol with an inter-relay interference (IRI) mitigation scheme, in a quasi-static environment with Rayleigh fading. In order to recover the half duplex loss of the transmission, we adopt a successive relaying (SR) strategy, coupled with reactive relay selection considering the Signal to Noise(More)
In future wireless mobile networks, data rate and quality of service are expected to be comparable to those of wired deployments. To achieve this target, novel architectures must be adopted, successfully countering the disadvantages of the wireless transmission. Inspired by that, cooperative relaying was proposed because of the various gains it introduces(More)
—In this paper we consider a simple cooperative network consisting of a source, a destination and a cluster of decode-and-forward relays characterized by the half-duplex constraint. At each time-slot the source and (possibly) one of the relays transmit a packet to another relay and the destination, respectively. When the source and a relay transmit(More)
In this work, we present a buffer-aided successive opportunistic relaying scheme that aims at improving the average capacity of the network when inter-relay interference arises between relays that are selected for simultaneous transmission and reception. We propose a relay selection policy that, by exploiting the benefits of buffering at the relays,(More)
In this work, we propose a buffer-aided successive opportunistic relay scheme where each time a relay-pair is selected with the target of rate maximization. Due to overlapping transmissions by the source and the relay which transmits to the destination, inter-relay interference arises. The efficient mitigation of inter-relay interference either through(More)
In this paper, we present a relaying scheme which combines the spectral efficiency of successive opportunistic relaying with the robustness of single-link selection. More specifically, we propose the min − power scheme that minimizes the total energy expenditure per time slot under an inter-relay interference (IRI) cancellation scheme. It is the first time(More)
Future Internet is expected to sustain a huge number of devices, many orders of magnitude higher than state-of-the-art network architectures and handle larger and unconventional information flows. Machine Type communications (MTC) will play a critical role in this evolution and thus both architectural and algorithmic enhancements to existing converged(More)
