1. A system, comprising: one or more motes, each mote being respectively operable to obtain and communicate sensor data related to at least one parameter; a computing device operable to communicate with the one or more motes, the computing device having a processing unit coupled to a data storage device; and one or more instructions loaded on the data storage device that, when executed by the processing unit, configure the computing device to: store an instance of sensor data related to the at least one parameter received from at least one mote of the one or more motes in a received data set in the data storage device; receive an input selection defining an event corresponding to a target-occurrence, the target-occurrence having a representative feature including at least one recognizable pattern of sensor data obtained by the at least one mote of the one or more motes and related to the at least one parameter; in response to the input selection defining the event corresponding to the target-occurrence, search the received data set for sensor data correlating to the representative feature of the target-occurrence; when received sensor data correlating to the representative feature of the target-occurrence is found, store the correlated received sensor data in a retained data storage; and delete the instance of sensor data related to the at least one parameter from the received data set according to a deletion sequence, wherein the deletion sequence includes deleting searched sensor data not correlated to the representative feature of the target-occurrence.
