Efficient online WiFi delivery of layered-coding media using inter-layer network coding
(
IEEE
, 2011 , Conference Paper)
A primary challenge in multicasting video in a wireless LAN to multiple clients is to deal with the client diversity - clients may have different channel characteristics and hence receive different numbers of transmissions ...
Performance analysis for truncated ARQ based DSFBC-CO-OFDM communication scheme
(
IEEE
, 2011 , Conference Paper)
We develop and analyze an ARQ (Automatic Repeat reQuest) based distributed space-frequency block code-orthogonal frequency division multiplexing protocol for cooperative communications (DSFBC-CO-OFDM). At PHY layer, space ...
Characterization of the indoor-outdoor radio propagation channel at 2.4 GHz
(
IEEE
, 2011 , Conference Paper)
We present the site-specific signal strength measurement results for path loss, shadowing, and fading in 2.4GHz band under typical harsh environment (high temperature 4050 C and humidity 8090%). We use spectrum analyzer ...
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 ...
The ICDAR2011 Arabic writer identification contest
(
IEEE
, 2011 , Conference Paper)
Arabic writer identification is a very active research field. However, no standard benchmark is available for researchers in this field. The aim of this competition is to gather researchers and compare recent advances in ...
Hybrid intelligent system for disease diagnosis based on artificial neural networks, fuzzy logic, and genetic algorithms
(2011 , Conference Paper)
Disease diagnosis often involves acquiring medical images using devices such as MRI, CT scan, x-ray, or mammograms of patients' organs. Though many medical diagnostic applications have been proposed; finding subtle cancerous ...
The 100 most influential persons in history": A data mining perspective
(2011 , Conference Paper)
Data mining has been widely applied in various domains; however, there have been limited studies into discovering hidden knowledge from factual data about selected groups of people with special characteristics. It is ...
