Forced spectrum access termination probability analysis under restricted channel handoff
(2012 , Conference Paper)
Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current ...
Cognitive transmission based on data priority classification in WSNs for Smart Grid
(2012 , Conference Paper)
Smart Grid integrates digital processing, sensor technology, automatic control and communication to the traditional power grid to achieve more efficient electricity distribution and management. Applying wireless sensor ...
Discovering influential users in micro-blog marketing with influence maximization mechanism
(2012 , Conference Paper)
Micro-blog marketing has become a main business model for social networks nowadays. On social networking sites (e.g., Twitter), micro-blog marketing enables the advertisers to put ads to attract customers to buy their ...
EM-MAC: An energy-aware multi-channel MAC protocol for multi-hop wireless networks
(2012 , Conference Paper)
We propose an energy-aware MAC protocol, referred to as EM-MAC, for multi-hop wireless networks with multi-channel access capabilities. EM-MAC relies on iMAC's efficient channel selection mechanism to resolve the medium ...
A novel P2P VoD streaming technique integrating localization and congestion awareness strategies
(2012 , Conference Paper)
The concept of the "future Internet" has evolved amongst researchers recently to relieve the tremendous pressure on the current Internet infrastructure to support the heterogeneous networking technologies, mobile devices, ...
Understanding the topologies of BitTorrent networks: A measurement view
(2012 , Conference Paper)
BitTorrent (BT) is one of the most popular Peer-to-Peer (P2P) network applications. Most characteristics (except the topology) of BT network have been examined extensively by measurement approaches. In this work, we deploy ...
An improved SVPWM method for multilevel inverters
(
IEEE
, 2012 , Conference Paper)
This paper proposes a new general Space Vector PWM (SVPWM) method for Multi-Level Inverters (MLI) based on a generalization of dwell-times calculation. The presented scheme is developed for Cascaded H-Bridge (CHB) inverter. ...
A wavelet-based passive islanding detection technique
(
IEEE
, 2012 , Conference Paper)
Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ...
Multilevel cascaded Z source inverter for PV power generation system
(
IEEE
, 2012 , Conference Paper)
The paper investigates the use of multilevel cascaded Z source inverter (MC-ZSI) for photovoltaic (PV) power generation system. The control of the proposed system will take into account the multilevel modulation scheme and ...
An original controller design for a grid connected PV system
(
IEEE
, 2012 , Conference Paper)
PV energy generation has been one of the most active research areas in the past decades due to its inexhaustibility and environmental-friendly aspects. However, the great deal is to utilize the solar energy effectively ...
