Future wireless communications system will have to make optimal use of
the resources available (such as device power and frequency bands), in
many varied scenarios.  So the attention of researchers has recently
moved to flexible and reconfigurable wireless systems.  Mobile Ad-Hoc
Networks (MANETs) are being developed - dynamic and self-configuring
systems of nodes (typically mobile devices) that allow communication
without the need for pre-existing infrastructure.  A promising way to
meet those increased requirements is by means of software-defined radio
(SDR). In SDRs, algorithms and parameters that are typically built-in as
dedicated hardware are instead implemented as choices in software
running on general applications or on embedded general computational
devices - thereby allowing a device to adapt to more networks and
situations. In this presentation, the challenge of implementing such
systems is discussed, and an existing MANET architecture is presented
which runs on the SDR Universal-Software-Radio-Peripheral (USRP)
platform. Our system supports Orthogonal Frequency Division Multiplexing
(OFDM), similar to the WiMax and LTE 4G standards, as well as
multiple-antenna transmission and enhanced MAC protocols.

 

Dr. Jafarkhani, a professor of Electrical Engineering and Computer
Science, is also Director of the CPCC.  He earned his B.S. degree from
Tehran University and his Ph.D. from the University of Maryland.  He
worked at AT&T Labs before coming to UCI; there he and his colleagues
invented space-time block coding, a technology that is now an active
area of research and practice. He is a Fellow of AAAS, an IEEE Fellow,
and the author of Space-Time Coding: Theory and Practice. 

Dr. Nikitopoulos is a postdoctoral researcher with the CPCC.  He
received his diploma in physics and his Ph.D. degree in
telecommunications from the National and Kapodistrian University of
Athens, Greece. From 2007 until 2010 he held a post-doctoral position in
Germany, and since January 2011 he has worked at the CPCC. He is also
actively involved in several research projects in Europe. 

 

The SURF-IT student working on the project is David Ho, a Computer
Science & Engineering major.
