Traffic Scheduling Technique for Smart Grid Advanced Metering Applications

June 5, 2012
Author(s)
Hamid Gharavi
In this paper, we present a multi-gate mesh network architecture that has been developed to ensure high performance and reliability under emergency conditions when a system expects to receive power outage notifications and exchanges. In order to handle the

Linear Dispersion Codes for Asynchronous Cooperative MIMO Systems

June 1, 2011
Author(s)
Hamid Gharavi
In this treatise, we propose a novel family of Asynchronous Cooperative Linear Dispersion Codes (ACLDCs), which is capable of maintaining full diversity in cooperative scenarios even at the presence of asynchronous reception. The linear dispersion

Multigate Communication Network For Smart Grid

June 1, 2011
Author(s)
Hamid Gharavi
It is envisioned that one of the most important issues in Smart Grid will be to design a network architecture that is capable of providing secure and reliable two-way communication from meters to other Smart Grid domains. While networking technologies and

Scanning the Issue Smart Grid: The Electric Energy System of the Future

June 1, 2011
Author(s)
Hamid Gharavi
This is an editorial article for a special issue on smart grid. The main objective is to report on some, if not all, of smart grid future technical challenges. While acknowledging its limited coverage, this issue offers a wide range of interesting

Selective Pixel Interpolation for Spatial Error Concealment

June 1, 2011
Author(s)
Hamid Gharavi, Yi Ge, Bo Yan, Kairan Sun
This paper proposes an effective algorithm for spatial error concealment with accurate edge detection and partitioning interpolation. Firstly, a new method is used for detecting possible edge pixels and their matching pixels around the lost block. Then

Multigate Mesh Routing for Smart Grid Last Mile Communications

May 1, 2011
Author(s)
Hamid Gharavi, Bin Hu
One of the most important issues in Smart Grid is to provide consumers with the knowledge of their energy usage, as well as allowing the utility to monitor and control the electric system components with real time status. This would require the design of a

Efficient Motion Vector Interpolation for Error Concealment of H.264/AVC

March 1, 2011
Author(s)
Hamid Gharavi
In video communications the compressed video stream is very likely to be corrupted by channel errors. In order to combat these channel errors, many methods have been proposed. In this paper, a new method for motion vectors (MVs) interpolation with the help

PYRAMID MODEL BASED DOWN-SAMPLING FOR IMAGE INPAINTING

September 2, 2010
Author(s)
Hamid Gharavi
Image inpainting is a useful and powerful technique for automatically restoring or removing objects in films and damaged pictures. In the last ten years, many excellent inpainting algorithms have been proposed after Bertalmio et al. [1]. However, no paper
