On the delay of finite buffered multi-hop relay wireless internet of things
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
The evolution of Internet of Things (IoT) as a new application in wireless networks mandates the utilization of wireless cooperative relaying to overcome the energy limitations of IoT devices. Multi-hop relaying is a ...
Non-data-aided SNR estimation for QPSK modulation in AWGN channel
(
IEEE Computer Society
, 2014 , Conference Paper)
Signal-to-noise ratio (SNR) estimation is an important parameter that is required in any receiver or communication systems. It can be computed either by a pilot signal data-aided approach in which the transmitted signal ...
Estimating the number of sources: An efficient maximization approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Estimating the number of sources received by an antenna array have been well known and investigated since the starting of array signal processing. Accurate estimation of such parameter is critical in many applications that ...
Secret key generation based on AoA estimation for low SNR conditions
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In the context of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. Therefore an accurate estimation of this characteristic is the core for reliable ...
Cognitive relay-sharing by using hierarchical modulation under interference constraints
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance in the presence of interference. It is assumed that the relay is shared simultaneously between ...
Towards Secure IoT Networks in Healthcare Applications: A Game Theoretic Anti-Jamming Framework
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
The internet of Things (IoT) is used to interconnect a massive number of heterogeneous resource constrained smart devices. This makes such networks exposed to various types of malicious attacks. In particular, jamming ...
Lifetime maximization with predictive power management in selective relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2009 , Conference Paper)
A diversity scheme which exploits the existence of a source-destination path to improve the lifetime and outage probability of a wireless selective relay network with Amplifyand-Forward (AF) relays is proposed and studied. ...
A simple cross correlation switched beam system (XSBS) for angle of arrival estimation
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with ...
