Optimal power allocation and relay selection in two-way multi-relay cooperative communication
(2013 , Conference Paper)
In this paper, we investigate the power allocation in two-way multi-relay assisted cooperative network in which the relays operate in decode-and-forward (DF) protocol. In the proposed method for choosing the best relay ...
Protocol design and stability analysis of cooperative cognitive radio users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
A single cognitive radio transmitter-receiver pair shares the spectrum with two primary users communicating with their respective receivers. Each primary user has a local traffic queue, whereas the cognitive user has three ...
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ...
Maximum throughput of a secondary user cooperating with an energy-aware primary user
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ...
Probabilistic band-splitting for a buffered cooperative cognitive terminal
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue to store, and then relay, the undelivered ...
Modulation-independent non-data-aided SNR estimator for OFDM signals in nakagami fading channels
(2013 , Conference Paper)
A signal-to-noise ratio estimator for OFDM signals in Nakagami-m fading channels is proposed. This estimator can be used with any signal constellation. It is an envelope-based non-data-aided estimator that makes use of ...
QoS-Aware Reliable Traffic Prediction Model under Wireless Vehicular Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
With the continuous progress of communication quality, the wireless vehicular networks (WVN) will surely be-come an inevitable part of future smart cities. Inside WVN where context is complicated and stochastic, quality ...
Hierarchical Federated Learning over HetNets enabled by Wireless Energy Transfer
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Training centralized machine learning (ML) models becomes infeasible in wireless networks due to the increasing number of internet of things (IoT) and mobile devices and the prevalence of the learning algorithms to adapt ...
BPFL: A Blockchain Based Privacy-Preserving Federated Learning Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Federated Learning (FL), which allows multiple participants to co-train machine Learning models without exposing local data, has been recognized as a promising method in the past few years. However, in the FL process, the ...
Understanding Digital Forensic Characteristics of Smart Speaker Ecosystems
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
With a built-in intelligent personal voice assistant providing QA services, smart speaker ecosystems combine multiple compatible components, including the internet of things (IoT) technology, mobile devices, and cloud ...
