Practical mobile communication systems suffer from time-variant channel fading and
cochannel interference, both of which give rise to challenges concerning strategy design …

One of the key challenges for cooperative relaying multi-rate wireless networks is the
integration and interaction of relaying with link adaptation algorithms, in particular under …

Mobile users often experience communication outage and low data rate. To efficiently and
economically cope with this problem, cooperative relaying is promising. It exploits wireless …

In this paper, we consider constellation design for decode-and-forward relay networks with
adaptive modulation, which improves the diversity combining gain by averaging over all …

This work is the second of a two-part series of papers on the effectiveness of cooperative
techniques in non-centralized carrier sense-based ad hoc wireless networks. While Part I …

We propose a Cooperative Rate Adaptation (CRA) MAC protocol based on the standard
CSMA/CA proto-col used in IEEE 802.11 wireless networks. The proposal provides …

This paper enhances the conventional scaled selection combiner (SSC) for decode-and-
forward (DF) relay networks using adaptive M-ary quadrature amplitude modulation (M …

ABSTRACT We propose a Cooperative Rate Adaptation MAC protocol based on the
standard CSMA/CA protocol used in IEEE 802.11 wireless networks. The main objective of …

Fast and reliable data transmission in wireless networks is hard to achieve due to
interference and fading. Interference limits spatial reuse in the network and fading leads to …

Broadly speaking, wireless ad hoc networks are permeated by cooperative behaviors. In
such systems, indeed, nodes have to continuously pool their resources to achieve goals that …
