Spatio-temporal sensor data management for context-aware services
2006
Proceedings of the 1st international workshop on Advanced data processing in ubiquitous computing (ADPUC 2006) - ADPUC '06
Preserved Fulltext
The facility of real-time analysis, which includes pe riodical evaluations of spatio-temporal conditions, enables application developers to outsource context-aware mecha nisms. ...
As described in this paper, we first examine mid dleware of context-aware services and our approaches. ...
Consequently, spatio-temporal manage ment is an inevitable function of context-aware systems. It provides spatio-temporal APIs for accessing the sensor data. ...
