Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...

On the fairness of frequency domain resource allocation in Wireless Mesh Networks A survey
(
IEEE
, 2011 , Conference Paper)
This article presents a concise survey of fairness-aware frequency domain resource allocation techniques in Wireless Mesh Networks (WMNs). Wireless mesh networks have emerged as a key technology for next generation application ...
Joint routing and resource allocation for delay sensitive traffic in cognitive mesh networks
(
IEEE
, 2011 , Conference Paper)
In this paper we study the problem of joint design of routing and resource allocation in cognitive radio based wireless mesh networks. Our study focuses on a cognitive system model in which secondary nodes have delay ...
The impact of inter-layer network coding on the relative performance of MRC/MDC WiFi media delivery
(
ACM
, 2011 , Conference Paper)
A primary challenge in multicasting video in a wireless LAN is to deal with the client diversity - clients may have different channel characteristics and hence receive different numbers of transmissions from the AP. A ...
Exposure assessment to WiFi access points by simulations and measurements
(
IEEE
, 2011 , Conference Paper)
This paper discusses two different approaches to assess exposure to indoor WiFi access points at two different frequency bands: 2.4GHz and 5GHz. The first analyzes the electromagnetic propagation in almost empty environments ...
Advanced experimental setup for the reliability characterization of radio-acoustic sensors in water pipes
(
IEEE
, 2011 , Conference Paper)
The paper presents the design and construction of a test bench for the analysis and certification of radio-acoustic sensors inside conduits filled with liquids. It is a brand new test-set that integrates the capability to ...
On relay assignment in network-coded cooperative systems
(
IEEE
, 2011 , Article)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
Threshold-based relaying in coded cooperative networks
(
IEEE
, 2011 , Article)
In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is ...
Two way opportunistic MAC protocol for Ad Hoc networks
(
IEEE
, 2011 , Conference Paper)
In this paper, network coding is introduced in relay based MAC protocols for bidirectional traffic to evaluate the performance in terms of throughput and energy. The idea of proposed scheme is to use high data rate nodes ...
