Verifying cloud service-level agreement by a third-party auditor
(
John Wiley & Sons, Ltd.
, 2014 , Article)
In this paper, we study the important issue of verifying service-level agreement (SLA) with an untrusted cloud and present an SLA verification framework that utilizes a third-party auditor (TPA). A cloud provides users ...
Coalitional double auction for spatial spectrum allocation in cognitive radio networks
(
IEEE
, 2014 , Article)
Recently, many dynamic spectrum allocation schemes based on economics are proposed to improve spectrum utilization in cognitive radio networks (CRNs). However, existing mechanisms do not take into account the economic ...
Secure and efficient data transmission for cluster-based wireless sensor networks
(
IEEE
, 2014 , Article)
Secure data transmission is a critical issue for wireless sensor networks (WSNs). Clustering is an effective and practical way to enhance the system performance of WSNs. In this paper, we study a secure data transmission ...
Limited feedback unitary precoding for MIMO full stream transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Limited feedback precoding (LFP) significantly improves multiple-input-multiple-output (MIMO) spatial multiplexing link reliability with a small amount of feedback from the receiver back to the transmitter. One of the key ...
Exploiting context severity to achieve opportunistic service differentiation in vehicular ad hoc networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Wireless Access in Vehicular Environment (WAVE) dictates primitives for intelligent transportation system (ITS) applications and services. The medium access control (MAC) layer in WAVE facilitates service differentiation. ...
Enabling smart cloud services through remote sensing: An internet of everything enabler
(
