Abstract:


      


      To
save energy, sensors must sleep most of the time. Thus sensors
coordinate to select among themselves those that will remain active
while preserving coverage of monitoring area. Active sensors then
coordinate among themselves to select a backbone for communication
coverage. Sensors in backbone are sensing in communicating while other
active sensors are idle (sensing only). Sensors may also specialize if
a heterogeneous network is considered. Data communication is performed
on a backbone. This talk discusses advantages and disadvantages of
commonly used methods for creating area and communication coverage:
clustering, grid partitioning, energy based activity decisions,
connected dominating sets, and sensor area coverage protocols. The use
of localized protocols with minimal communication overhead is
emphasized.

      Ivan
Stojmenovic received Ph.D. degree in mathematics. He held positions in
Serbia, Japan, USA, Canada, France and Mexico. He published over 200
different papers (including over 30 book chapters), and edited four
books on wireless, ad hoc and sensor networks and applied algorithms
with Wiley/IEEE. He is currently editor of several journals including
IEEE TPDS, and founder and editor-in-chief of three journals.
Stojmenovic is in the top 0.56% most cited authors in Computer Science
(Citeseer 2006). One of his articles was recognized as the Fast
Breaking Paper, for October 2003 (as the only one for all of computer
science), by Thomson
ISI Essential Science Indicators. He (co)chaired program committees for
IEEE MASS 2007 and 2004, IEEE AINA 2007, IEEE MASS-04, InterSense-06,
EUC-05, WONS-05, MSN-05-06, ISPA-05 and -07, co-chaired workshops at
IEEE MASS-06, IEEE ICDCS 2003-2007; IEEE LCN-05-06, HICSS, 2000, 2002,
2003; ICPDS-02; ICPP-00;  and was program committee member of
over 100 conferences since 2004.
