TITLE:  Wireless Multimedia Sensor Networks: Challenges and Solutions in
Resource-Constrained Cross Layer Design

TIME:  3:30 PM

LOCATION:  GMCS 214

SPEAKER:  Dr. Wei Wang. San Diego State University

ABSTRACT:  With the steady developments of multimedia communications in low
cost Wireless Multimedia Sensor Networks (WMSN), joint design of multimedia
compression, secure communication and energy efficient resource allocation
algorithms is now a key issue. This presentation gives a fundamental
understanding of the relationship between high level multimedia signal
processing and low level wireless networking protocol design. In
particular, this work uniquely addresses two fundamental challenges: 1)
optimizing cross layer communication architecture with energy efficiency
and service quality assurance for WMSN; and 2) effective protection and
authentication of large-sized digital multimedia streams over wireless
links. By unifying multimedia selective encryption and stream
authentication as well as the inborn unequal importance nature of the
multimedia streaming, the resource allocation efficiency can be
significantly improved with limited computation and communication overheads.
