Distance-Sensitive Information Brokerage in Sensor Networks [chapter]

Stefan Funke, Leonidas J. Guibas, An Nguyen, Yusu Wang
2006 Lecture Notes in Computer Science  
In a sensor network information from multiple nodes must usually be aggregated in order to accomplish a certain task.  ...  The presented algorithms rely purely on the topology of the communication graph of the sensor network and do not require any geographic location information.  ...  As sensor networks scale to larger sizes, the issue of information locality becomes more important.  ...
