摘要:
A method and apparatus for tracking target objects includes a network of unidirectional sensors which correspond to nodes on the network. The sensors identify the presence of a target object, determine a first criteria for the relationship of the target object to the sensors and send a message to sensors neighboring the sensor. The message includes a unique identification of the target object and the first criteria. The sensors are ranked to determine which of the sensors should head a cluster of sensors for tracking the target object. Clusters are propagated and fragmented as the target object moves through a field of sensors.
摘要:
Illustrative embodiments of integrated pest management (IPM) systems and electronic insect monitoring devices (EIMDs) are disclosed. In some embodiments, the EIMDs may each comprise a lure for attracting at least one target insect species, one or more sensors that generate one or more output signals in response to an insect approaching the lure, and an electronic controller configured to determine if the insect approaching the lure belongs to the at least one target insect species using the one or more output signals. In some embodiments, the IPM system may comprise a plurality of EIMDs configured to communicate over a wireless network shared by the plurality of EIMDs.
摘要:
Embodiments of a method for controlling access to a shared communications medium by a plurality of nodes are disclosed. The method may comprise predicting, for each node of the plurality of nodes, whether an event will occur within a sensing field of that node at a future time and adapting a communications schedule of each node in response to the prediction regarding that node. Wireless sensor networks and computer readable media implementing embodiments of a method for controlling access to a shared communications medium by a plurality of nodes are also disclosed.
摘要:
The present disclosure relates to a sensor network including a plurality of nodes, each node having a directional sensor, a communication module, and a processor configured to receive local measurements of a calibration object from the directional sensor, receive additional measurements of the calibration object from neighboring nodes via the communication module, estimate an initial set of calibration parameters in response to the local and additional measurements, receive additional sets of calibration parameters from neighboring nodes via the communication module, and recursively estimate an updated set of calibration parameters in response to the additional sets of calibration parameters. Additional systems and methods for calibrating a large network of camera nodes are disclosed.
