| Filip Perich is a Software Functional Manager and Senior Software
Engineer at Shared Spectrum Company and an Adjunct Assistant Professor
at University of Maryland Baltimore County (UMBC). He is
an experienced project manager and a team leader of military and
commercially based projects. He is instrumental in a concept
design, proposal development, product development and fielding,
and in securing government-funded research awards. His primary
research focus is in applications of Data Management and Artificial
Intelligence to problems in distributed systems, particularly with
an emphasis on wireless mobile / pervasive ad hoc networks. Currently,
he is developing policy-based next generation (XG) communications
technologies for enabling tactical mobile users to utilize efficiently
available radio frequency spectra with minimal interference to
existing legacy radios and secure, policy-based wide-area network
configuration systems. He received Ph.D. and M.S. degrees
in Computer Science from UMBC, and a B.A. degree in Mathematics
from Washington College in Maryland. Perich is an author
of over 25 refereed publications. He is professionally active
in advising graduate students, serving on Ph.D. committees, and
in organizing conferences and workshops on Artificial Intelligence,
Data Management, E-Commerce, Networks, Security, and Semantic Web.

Perich's research interest can be categorized under the broad
umbrella of proactive pervasive computing. His current primary
research focus is on data management and intelligent agent
software in distributed systems, particularly applicable for
mobile / pervasive ad hoc networks. In his academic and commercial
research, Perich investigates the underlying issues from the
perspective of autonomous intelligence, data management, networking,
security, privacy, trust and the Semantic Web. His work focuses
on building intelligent distributed systems in order to enable
independent, mobile entities - including handhelds, wearable
computers, computers in vehicles, computers embedded in the
physical infrastructure, and sensors - to become more autonomous,
dynamic and adaptive with respect to their environments.
As part of his Ph.D. research and current ongoing academic
research, Perich has been exploring the issues associated
with enabling automated, policy-controlled pervasive computing
environments. Perich tackles these issues from the data management
perspective where pervasive computing environments can be
represented as a special instance of mobile distributed database
systems. As such, they inherit problems traditionally found
in mobile databases; however, they also introduce additional
issues due to the peer-to-peer model of interaction. These
problems are due to spatio-temporal variations of data and
data source availability, the lack of a global catalog and
schema and problems related to collaboration and reconnection
among devices.
To address these issues, Perich is using a semantically
rich language to define ontologies for describing data and
user's preferences in terms of policies. Using this information,
he is defining protocols for a semantic-based data discovery.
The protocols overcome the absence of a global catalog schema.
Perich is also defining protocols for data-centric routing
of information among peer devices in mobile ad-hoc networks.
Additionally, in order to overcome other introduced problems,
Perich is focusing on defining models that enable devices
to query their peers, to perform join operations over peer
streams, and to improve transaction commit rate. He also
uses the semantic description of data and user preferences
in order to improve caching performance. The semantic-based
cache replacement algorithm vastly improves the cache-hit
rate as Perich has shown in an accepted publication in IEEE's
Transactions on Knowledge and Data Engineering. Recently,
Perich has also started exploring the idea of improving
accuracy of query results based on distributed trust and
belief management. Perich is implementing a lightweight
framework, called MoGATU, for experimental purposes and
to validate his approach. Overall this work has lead to
several journal and conference publications and to two papers
currently under a review.
Perich also collaborated on developing an architecture for
smart spaces, called Vigil. In this project, Perich and his
colleagues developed a secure environment composed of transparent
services that can be automatically discovered and accessed
by users using mobile devices communicating using Bluetooth,
IR or WLAN, or via voice.
Perich is employed at Shared Spectrum Company where he is
architecting and developing next generation (XG) technologies
for policy-controlled software-based dynamic spectrum access
radios and for automated wide-area network configuration
and management. Prior to joining Shared Spectrum Company,
Perich was employed at Cougaar Software, Inc., where he developed
novel military and commerical intelligent-agent-based distributed
middleware with an emphasis on C4ISR cognitive data fusion,
visualization, and control. During the summer of 2003 Perich
was an IBM Fellow at IBM Centre for Advanced Studies, Toronto
Laboratories, Canada working in the E-Commerce Emerging Technology
Department where he developed a voice-channel prototype for
the IBM WebSphere Commerce Portal business solution. During
the summer of 2002, Perich then interned with Dr. Bernard
Burg at Hewlett-Packard Labs in Palo Alto, CA where he developed
a knowledge repository web service for collecting and reasoning
over context-dependent information annotated in RDF.
