Carrier assignment algorithms for OFDM-based multi-carrier wireless networks with channel adaptation
(2008)
We study carrier assignment in a single-cell multiuser OFDM multi-carrier system so as to satisfy user rate requirements with minimal resources. Different users experience different quality in different carriers due to ...
Cross-layer adaptive techniques for throughput enhancement in wireless OFDM-based networks
(2006)
Although independent consideration of layers simplifies wireless system design, it is inadequate since: 1) it does not consider the effect of co-channel user interference on higher layers; 2) it does not address the impact ...
A framework and experimental study for discrimination of collision and channel errors in wireless LANs
(2012)
A fundamental unresolved problem in wireless networks is that of distinguishing packet errors that are caused by deteriorated link conditions and noise, from errors that occur due to packet collisions. In this paper, we ...
Challenges in Demand Load Control for the Smart Grid
(2011)
The ground to address challenges in demand load control for the smart power grid is now more fertile than ever, due to advances in communication infrastructures and the creation of a two-way channel for real-time communication ...
Adaptive channel allocation in OFDM/SDMA wireless LANs with limited transceiver resources
(2004)
Smart antennas increase capacity of wireless systems by allowing channel reuse by several users in the same cell through space division multiple access (SDMA). Orthogonal Frequency Division Multiplexing (OFDM) creates ...
An experimental framework for data gathering and analysis in wireless sensor networks
(2011)
In the last decade testbeds have been set-up to evaluate network protocols and algorithms under realistic settings. Moreover, wireless sensors have lately been integrated into testbeds in order to simulate application ...
An integrated chassis manager card platform featuring multiple sensor modules
(2012)
The gradually growing demand for experimentation of protocols designed for wireless networks in real environments has resulted in the development of experimental network facilities (testbeds). Most currently deployed ...
An experimental framework for channel sensing through USRP/GNU radios
(2012)
In the last decade testbeds have been set-up to evaluate network protocols and algorithms under realistic settings. In order to draw solid conclusions about the corresponding experimental results, it is important for the ...
Energy aware buffer aided cooperative relay selection
(2014)
In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ...
NITOS mobile monitoring solution: Realistic energy consumption profiling of mobile devices
(2014)
The unprecedented penetration of "smart" mobile devices in everyday use case scenarios, along with their energy greedy profile have motivated researchers in the field of wireless networking, towards reducing energy consumption ...
