Joint mode selection, channel allocation and power assignment for green device-to-device communications
(
IEEE Computer Society
, 2014 , Conference Paper)
Device-to-Device (D2D) communication has emerged as a promising technique for improving capacity and reducing power consumption in wireless networks. Most existing works on D2D communications either targeted CDMA-based ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
Small data dissemination for wireless sensor networks: The security aspect
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
In wireless sensor networks small data dissemination protocols are used to adjust configuration parameters of sensors, or distribute management commands and queries to sensors. For security reasons every disseminated data ...
Joint physical-application layer security for wireless multimedia delivery
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
In recent years, there have been increasing demands for the security of wireless multimedia applications. Essentially, wireless networks, compared to traditional wired networks, are more likely to suffer from malicious ...
