Abstract
A method and network for detecting multiple events is provided. The method includes detecting at least one subordinate event constituting a superordinate event, determining whether another subordinate event constituting the superordinate event exists in a time window other than a current time window in which the detected subordinate event is included, and determining that the superordinate event has occurred and reporting the determination, if the subordinate events constituting the superordinate event exist within a duration of the superordinate event.
Claims13
A sensor network, comprising:
- sensor nodes including multiple sensors for detecting primitive events;
- and
- a coordinator node for determining whether the primitive events detected in the sensors are included in a duration of a complex event, and determining that the complex event has occurred if the primitive events are included in the duration.
A method for detecting multiple events, comprising the steps of:
- detecting at least one subordinate event constituting a superordinate event;
- determining whether another subordinate event constituting the superordinate event exists in a time window other than a current time window in which the detected subordinate event is included;
- and
- determining that the superordinate event has occurred and reporting the determination, if the subordinate events constituting the superordinate event exist within a duration of the superordinate event.
A method for detecting multiple events, comprising the steps of:
- (1) reporting a first primitive event detected in a sensor node in a bottom layer;
- (2) determining whether there exists a subordinate event other than the first primitive event constituting a superordinate event;
- and
- (3) determining a relation between the first primitive event and the subordinate events, if the subordinate event exists.
