2. Virtual Reality Platform to Study RF Propagation in Body Area Networks
Topic: Wireless
Published: 12/2/2012
Authors: Kamran Sayrafian, John G Hagedorn, Wen-Bin Yang, Judith Ellen Terrill
Abstract: Design of efficient wireless communication protocols for body area networks requires in-depth understanding of the propagation media i.e. the human body. As obtaining large amount of data for many scenarios and use-cases via physical experiment i ...

3. A Low-Complexity Solution to Decode Diversity-Oriented Block Codes in MIMO Systems with Inter-Symbol Interference
Topic: Wireless
Published: 10/1/2012
Authors: Hamid Gharavi, Chong Xu
Abstract: In this paper we firstly propose a block-code based general model to combat the Inter-Symbol Interference (ISI) caused by frequency selective channels in a Multi-Input Multi- Output (MIMO) system and/or by asynchronous cooperative transmissions. The ...

5. Traffic Scheduling Technique for Smart Grid Advanced Metering Applications
Topic: Wireless
Published: 6/5/2012
Author: Hamid Gharavi
Abstract: 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 hand ...

6. Battery Discharge Characteristics of Wireless Sensors in Building Applications
Topic: Wireless
Published: 4/11/2012
Authors: Wenqi Guo, William M Healy, Mengchu Zhou
Abstract: Sensor nodes in wireless networks often use batteries as their source of energy, but replacing or recharging exhausted batteries in a deployed network can be difficult and costly. Therefore, prolonging battery life becomes a principal objective ...

7. Ant-Colony Based Near-ML Block Decoder in Asynchronous Cooperative MIMO Systems Using a Linear Dispersion Structure
Topic: Wireless
Published: 6/5/2011
Authors: Hamid Gharavi, Chong Xu
Abstract: The linear dispersion structure is employed to accommodate the dynamic topology of cooperative networks, as well as to achieve higher throughput than conventional space-time codes based on orthogonal designs. Asynchronous Cooperative Liner Dispersio ...

8. Pixel Interlacing Based Video Transmission for Low-complexity Intra-frame Error Concealment
Topic: Wireless
Published: 6/1/2011
Author: Hamid Gharavi
Abstract: When multi-path fading and interference frequently disrupts a mobile radio communication system, it can seriously undermine its reliability for transmission of compressed video signals. In this paper, we present a pixel interlacing based video transm ...

9. Selective Pixel Interpolation for Spatial Error Concealment
Topic: Wireless
Published: 6/1/2011
Authors: Hamid Gharavi, Yi Ge, Bo Yan, Kairan Sun
Abstract: 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 ...

10. A Joint Vehicle-Vehicle/Vehicle-Roadside Communication Protocol for Highway Traffic Safety
Topic: Wireless
Published: 5/1/2011
Author: Hamid Gharavi
Abstract: In this paper, a joint vehicle-vehicle/vehicle-roadside communication protocol is proposed for cooperative collision avoiding in Vehicular Ad Hoc Networks (VANETs). In this protocol, emergency warning messages are simultaneously transmitted via Veh ...
