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.
