Analyzing cognitive network access efficiency under limited spectrum handoff agility
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Most existing studies on cognitive-radio networks assume that cognitive users (CUs) can switch to any available channel, regardless of the frequency gap between a target channel and the current channel. However, due to ...

This paper provides an overview of the Internet of Things (IoT) with emphasis on enabling technologies, protocols, and application issues. The IoT is enabled by the latest developments in RFID, smart sensors, communication ...
Distributed resource allocation in cloud-based wireless multimedia social networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
With the rapid penetration of mobile devices, more users prefer to watch multimedia live-streaming via their mobile terminals. Quality of service provision is normally a critical challenge in such multimedia sharing ...
A unified approach for calculating the outage performance of two-way af relaying over fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Amplify-and-forward-based two-way relaying (TWR-AF) promises significant benefits in wireless networks. In this paper, we aim to obtain unified expressions to determine the outage probability of TWR-AF, regardless of ...
Accountable and privacy-enhanced access control in wireless sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In general, owners and users of wireless sensor networks (WSNs) are different entities. A user may want to hide his/her data access privacy from anyone else including the network owner and, at the same time, users who ...
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
(2013 , Article)
This paper studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically derive and evaluate the achievable performance of these ...
A promising non-orthogonal multiple access based networking architecture: Motivation, conception, and evolution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Since it can offer higher spectral efficiency by granting the served data to share the same spectrum resource synchronously, NOMA is considered as a bright multiple access technique for future wireless networks. Accommodating ...
Automatic Modulation Classification for Low SNR Digital Signal in Frequency-Selective Fading Environments
(
Kluwer Academic Publishers
, 2015 , Article)
In this research, a classifier is proposed for automatic modulation classification of some common modulation schemes, i.e., BPSK, QPSK, 8-PSK and 16-QAM. Our proposed classifier considers multipath fading effects on the ...
Auction-based relay power allocation: Pareto optimality, fairness, and convergence
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
It is well known that a cooperative communication technique can offer significant energy saving improvements. In particular, the efficient relay resource allocation makes energy saving practically appealing. In this work, ...
Secure and distributed data discovery and dissemination in wireless sensor networks
(
IEEE Computer Society
, 2015 , Article)
A data discovery and dissemination protocol for wireless sensor networks (WSNs) is responsible for updating configuration parameters of, and distributing management commands to, the sensor nodes. All existing data discovery ...
