Abstract:
1. A method comprising, by one or more computer systems: from an aggregator in a sensor network, accessing a plurality of sensor data from a plurality of sensors in the sensor network; at the aggregator, aggregating the sensor data from the plurality of sensors for communication to an indexer in the sensor network, the aggregation of the sensor data comprising: deduplicating the sensor data; validating the sensor data to block malicious data from reaching the indexer; formatting the sensor data for processing of the sensor data at the indexer; generating, based on information in the sensor data, metadata for the sensor data configured for indexing of the sensor data by the indexer, the metadata identifying one or more pre-determined attributes of the sensor data; appending the metadata to the sensor data; and time-stamping the sensor data with one or more time stamps; and from the aggregator, communicating the aggregated sensor data to the indexer in the sensor network, the indexer being configured to index the aggregated sensor data according to a multi-dimensional array for querying of the aggregated sensor data along with a plurality of other aggregated sensor data, one or more first ones of the dimensions of the multi-dimensional array comprising time and one or more second ones of the dimensions of the multi-dimensional array comprising one or more of the pre-determined sensor-data attributes; wherein deduplicating the sensor data comprises: detecting similar sensor data from the two or more sensors; communicating a control message in the sensor network instructing one or more of the two or more sensors to pause communication of their sensor data.
