Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and ...
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ...
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 ...
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 ...
Atmospheric turbulence effect on hybrid FSO/RF systems
(
IEEE Computer Society
, 2017 , Conference Paper)
This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ...
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 ...
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 ...
Exact closed form expressions for outage probability of GSC receivers over Rayleigh fading channel subject to self-interference
(
IEEE
, 2010 , Conference Paper)
Previous work on performance analyses of generalized selection combining (GSC) RAKE receivers based on the signal to noise ratio focused on the development of methodologies to derive exact closed-form expressions for various ...
Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
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 ...
