In-Network Surface Simplification for Sensor Fields Brian Harrington and Yan Huang   View Paper (PDF)   Return to Session 2: Sensor Networks Abstract Recent research literature on sensor network databases has focused on finding ways to perform in-network aggregation of sensor readings to reduce the message cost. However, with these techniques information about the state at a particular location is lost. In many applications such as visualization, finite element analysis, and cartography, constructing a field from all sensor readings is very important. However, requiring all sensors to report their readings to a centralized station adversely i ... ©2006 Association for Computing Machinery
