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 ...
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 ...
Impact of channel estimation error on bidirectional MABC-AF relaying with asymmetric traffic requirements
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
Channel estimation error results in severe performance deterioration in wireless networks. In this paper, we study the impact of imperfect channel estimation (ICE) on the outage performance of bidirectional relaying where ...
Carrier aggregation for LTE-advanced: Uplink multiple access and transmission enhancement features
(2013 , Article)
Multiple access and transmission enhancement in support of carrier aggregation techniques has been actively studied in the 3GPP LTEAdvanced standardization process of the nextgeneration mobile broadband communication ...
An enhanced public key infrastructure to secure smart grid wireless communication networks
(2014 , Article)
It is expected that the smart grid will radically add new functionalities to legacy electrical power systems. However, we believe that this will in turn introduce many new security risks. With the smart grid's backbone ...
A measurement study on the topologies of BitTorrent networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
BitTorrent (BT) is a widely-used peer-to-peer (P2P) application. Most of BT's characteristics (except the topology) have been studied extensively by measurement approaches. In this paper, we deploy a measurement system to ...
DVF-fog: Distributed virtual firewall in fog computing based on risk analysis
(
Inderscience Publishers
, 2019 , Article)
To eliminate network saturation during data exchanges, fog computing is deployed as the technology that benefits from both cloud computing and internet of things (IoT) paradigms. Therefore, we focus on network access control ...
