Recent Research Activities:

 

Ř      Music Telepresence (partially supported by NSF Award #0555457 and by WSU Research Council through Research Initiation Award #241699 and Research Challenge Award #666415)

(with The University of Rochester, Eastman School of Music, The University of Miami, Frost School of Music, and New World Symphony.)

Internet mediated telepresence has the potential to transform society by eliminating the physical barriers to collaboration. However, it has yet to reach the ideal of providing a medium-transparent, immersive visual and audio link between remote locations. The goal of this project is to advance the state of Internet-based telepresence in the context of a number of demanding musical applications. The particular musical applications to be addressed in this research range from high-quality multicast streaming of musical performances to robust, low-latency, interactive full-duplex unicast transport to enable real-time distributed interactive performances, collaboration and rehearsal, musical training and education.

 

Ř      Wireless Ad Hoc and Sensor Networks  (partially supported by NSF Award # 0454170 and the Ohio 3rd Frontier Project - “Wright Center for Sensor System Engineering”, collaborate with B. Wang, G. Dong and Z. Wu)

The objective of this project is to study new sensor network architectures for improved connectivity, energy conservation, and reliability; to evaluate security protocols; to design new security mechanisms and resilience schemes in defense of faults and attacks; and develop region-based event monitoring applications. The infrastructure will also support education at Wright State University by use in undergraduate and graduate capstone courses and research.

 

Ř      A Cross-Layer Design Approach for Providing Differential QoS and High-Quality Multimedia Service Over Next Generation Wireless Networks (partially supported by NSF Award #0708469 and by WSU through Research Challenge Award #665666, collaborate with B. Wang and Z. Wu)

The objective of this project is to jointly optimize the power consumption and data delivery quality under tight time-delay constraints using a cross-layer design and implementation approach employing adaptive modulation, power control and JSCC, resulting in a more power-efficient, more spectrally efficient, more reliable and robust system design enabling differential QoS and high-quality multimedia services over next generation mobile wireless networks.

 

Ř      Multi-Hop Free Space Optics Last-Mile Networks Using Very Low-Cost Components (partially supported by NSF Award#0230787, collaborate with P. Dutta and S. Kalyanaraman at RPI)

The project will build low-cost FSO interconnection systems, complemented with relatively cheap and programmable electronic components after l0s-l00s of opto-electronic (OEO) hops. It is also proposed to investigate spatial coding and redundancy techniques at the electronic hops taking advantage of the particular spatial structures (eg: 2d array, spherical etc). An examination of fundamental network capacity limits for FSO-based fixed and ad-hoc configurations, and fundamental power-per-bit achievable in future sensor networks will be done. Evaluating the impact of such multi-hop FSO networks on the performance of TCP/IP, VoIP and multimedia applications.

 

Ř      Composable Simulation Designs for Biological Network Discovery and Applications (partially supported by DAGSI through the Scholarship Program)  

Molecular biology has led to remarkable progress, with our understanding of biological systems currently focused mainly on the identification of genes and functions of the products and components of a larger system.  The next major paradigm shift in our understanding of biological systems will be to build dynamic interrelationships on the details revealed to us by these molecular data: these dynamic relationships differentiate a gelatinous mass of interspersed non-interconnected building block molecules, from the simplest of life forms whose molecular machinery is working as a coherent multi-level networked system. The goal of this project is to expand and build on the statistical analysis approach to the experimental biological network analysis approach, and to establish a methodology for understanding biological networks at levels from gene regulation and transcription, protein and protein complexes, metabolic pathways, neural systems, as well as high level cognition; to apply some insights obtained for engineering system design, such as wireless and sensor networks. 

 

Ř      Compression of Compound Images and Videos for Information-Rich Applications over Network-Enabled Embedded Systems  

This project targets on enabling ‘dumb” devices to behave as if much more “intelligent” to users, at very low costs and power. It is possible to improve the features supported by devices with embedded systems by increasing the processor computing power, but this always results in higher costs, complexity, and power consumption. An interesting alternative is to use the growing networking infrastructures to do remote processing and visualization, with the embedded system mainly responsible for communications and user interaction. In this project we investigate how compression techniques can make some of these solutions more bandwidth-efficient, enabling devices to simply decompress very rich graphical information and user interfaces that had been rendered elsewhere.
