In mobile systems, the requirements on event detection are fundamentally different to those in distributed systems. Composite event detection must be driven not just by the time of occurrence of an event, but also by its location of occurrence. Hence, the theory of composite event detection, as applied in traditional DEBS, needs to be reassessed. In this short paper, we motivate the notion of spatio-temporal event detection and propose the base operators of a spatio-temporal event language.
