Proactive power allocation and caching node selection for regular service guarantees
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper studies the potential of proactive resource allocation to prolong the communication sessions in networks with limited energy budgets and stringent quality-of-service (QoS) requirement, particularly a regular ...
Residual self-interference analysis for full-duplex OFDM transceivers under phase noise and I/Q imbalance
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
In this letter, we investigate the detrimental effects of phase noise (PN) and in-phase/quadrature (I/Q) imbalance (IQI) on full-duplex OFDM transceivers. In particular, we derive a closed-form expression for the average ...
Centralized and Distributed Cognitive Relay-Selection Schemes for SWIPT Cognitive Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the model of a single primary-transceiver pair with multiple secondary-transceiver pairs. The secondary pairs can act as relays for the primary transmitter enabling access to its channel resources. Each ...
Design Challenges of Multi-UAV Systems in Cyber-Physical Applications: A Comprehensive Survey and Future Directions
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Unmanned aerial vehicles (UAVs) have recently rapidly grown to facilitate a wide range of innovative applications that can fundamentally change the way cyber-physical systems (CPSs) are designed. CPSs are a modern generation ...
Secure mHealth IoT data transfer from the patient to the hospital: A three-tier approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
eHealth and mHealth applications are gaining increasing importance with advances in the IoT and the ubiquity of sensor deployments. Measured IoT mHealth data needs to be captured, transmitted, and stored securely, without ...
Optimal cooperative cognitive relaying and spectrum access for an energy harvesting cognitive radio: Reinforcement learning approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we consider a cognitive setting under the context of cooperative communications, where the cognitive radio (CR) user is assumed to be a self-organized relay for the network. The CR user and the primary user ...
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 ...
Robust secret key extraction from channel secondary random process
(
John Wiley and Sons Ltd
, 2016 , Conference Paper)
The vast majority of existing secret key generation protocols exploit the inherent randomness of the wireless channel as a common source of randomness. However, independent noise added at the receivers of the legitimate ...
Power-optimal feedback-based random spectrum access for an energy harvesting cognitive user
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we study and analyze cognitive radio networks in which secondary users (SUs) are equipped with energy harvesting (EH) capability. We design a random spectrum sensing and access protocol for the SU that ...
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 ...
