Temporal Predicate Detection Using Synchronized Clocks
November 2007 (vol. 56 no. 11)
pp. 1578-1584
Advances in clock synchronization techniques allowan approximated global time in ubiquitous environments. Thispaper presents an event stream based on-line algorithm that fusesthe data reported from the processors in such a network to detecttime-based predicates. The algorithm has low space, time, andmessage complexities. The paper also considers the detection ofsimultaneous events, as a special case.
