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 ...
A multi-parameter based vertical handover decision scheme for M2M communications in HetMANET
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The Machine-to-Machine (M2M) communication has the potential to connect millions of devices in the near future. Since they agree on this potential, several standard organizations need to focus on improved general architecture ...
Detecting the greedy spectrum occupancy threat in cognitive radio networks
(
IEEE Computer Society
, 2014 , Conference Paper)
Recently, security of cognitive radio (CR) is becoming a severe issue. There is one kind of threat, which we call greedy spectrum occupancy threat (GSOT) in this paper, has long been ignored in previous work. In GSOT, a ...
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 ...
Impact of execution time on adaptive wireless video scheduling
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Adaptive wireless video scheduling has been widely studied to improve network performance. However, the majority of existing scheduling algorithms assume that they are able to converge instantaneously to adapt to a dynamic ...
Design and implementation of credit-based resource allocation protocol for DSA systems
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper designs, implements, and evaluates an efficient dynamic spectrum access (DSA) protocol for cognitive radio networks. The proposed protocol relies on the concept of credit value to allocate resources among users ...
Securing vehicle-to-grid communications in the smart grid
(2013 , Article)
Using vehicle-to-grid (V2G) services, battery vehicles (BVs) may help the smart grid alleviate peaks in power consumption. However, wireless communications infrastructure between BVs and the smart grid also introduce severe ...
