In this paper, we propose a new relay selection scheme for half-duplex relays with buffers.
The proposed scheme is referred to as max-max relay selection (MMRS) since the relays …

In this correspondence, an adaptive cooperation diversity scheme with best-relay selection
is proposed for multiple-relay cognitive radio networks to improve the performance of …

Abstract Machine-to-machine (M2M) communications emerge to autonomously operate to
link interactions between Internet cyber world and physical systems. We present the …

Cooperative diversity is a relatively new technique that can be used to improve the
performance of the wireless networks. The main advantage of this technique is that the …

We study the effect of outdated channel state information on the outage and error rate
performance of amplify-and-forward (AF) relay selection, where only one out of the set of …

In this paper, we investigate the end-to-end performance of dual-hop proactive decode-and-
forward relaying networks with Nth best relay selection in the presence of two practical …

This paper addresses the multiplexing loss that occurs in relay networks due to causality of
relays and the half-duplex constraint. We devise relay selection methods to recover the …

We consider an amplify-and-forward (AF) cooperative diversity system where a source node
communicates with a destination node directly and indirectly (through multiple relays). In …

Future generations of cellular communications requires higher data rates and a more
reliable transmission link with the growth of multimedia services, while keeping satisfactory …

Relay selection is crucial in improving the performance of wireless cooperative networks.
Most previous works for relay selection use the current observed channel conditions to make …
