Secure DoF for the MIMO MAC: The case of knowing eavesdropper's channel statistics only
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Physical layer security has attracted research attention as a means to achieve secure communication without the need for complicated upper layer encryption techniques. The secure degrees of freedom (SDoF) of various networks ...
Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
(
Wiley Blackwell
, 2016 , Article)
This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
Diversity-multiplexing tradeoff for log-normal fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Optimization of effective area spectral efficiency for wireless communications systems under Nakagami-m fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we present an optimization of the effective area spectral efficiency (EASE) metric for point-to-point transmission systems, and decode-and-forward (DF) relaying communications networks under Nakagami-m fading ...
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ...
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 ...
Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
On spectrum sharing between energy harvesting cognitive radio users and primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Optimum power and rate allocation in cluster based video sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In a wireless video sensor network (WVSN), each video sensor node consumes a significant amount of power on video compression in addition to the required power for communication. Therefore, the power optimization is a more ...
QUMESH: Wireless mesh network deployment and configuration in harsh environment
(
IEEE
, 2012 , Conference Paper)
The link delivery probability in a wireless mesh network is most accurately determined only by experiment, as it depends on many factors, including environment characteristics, transmission power, distance between transmitter ...
