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 for communication to an indexer in the sensor network, the aggregation of the sensor data comprising;

    substantially deduplicating the sensor data;

    substantially 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 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; 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.
