Abstract: In one embodiment, a method includes receiving a summary of statistics concerning a sensor node in a sensor network that comprises a plurality of sensor nodes, the statistics having been generated based on one or more of sensor data from a sensor at the sensor node, communication to the sensor node from one or more other sensor nodes in the sensor network, or communication from the sensor node; analyzing the summary; and applying based on the analysis one or more predetermined polices to one or more of the sensor nodes or the sensor network.

Abstract: In one embodiment, a method includes generating a set of statistics concerning a sensor node in a sensor network based on one or more of sensor data from a sensor at the sensor node, communication to the sensor node from one or more other sensor nodes in the sensor network, or communication from the sensor node; determining based on a subset of the set of statistics whether a predetermined anomalous event correlated with the subset has occurred; and, if the predetermined anomalous event has occurred, generating a summary of the subset and communicating it to a police node in the sensor network.

Abstract: In one embodiment, a method includes accessing first information identifying a sensor-data set that includes sensor-data from multiple sensor-data streams from multiple sensors over a period of time, with the sensor data from the sensor-data streams having been combined with each other based on a relationship of the sensor data to a sensor subject; accessing second information identifying one or more offers to purchase the sensor-data set; and matching one of the offers with the sensor-data set to facilitate a purchase of the sensor-data set based at least on the one of the offers matched to the sensor-data set.

Abstract: In one embodiment, a method comprises accessing a statistic concerning a sensor node in a sensor network, the statistic being based on one or more of sensor data from a sensor at the sensor node, communication to the sensor node from one or more other sensor nodes in the sensor network, or communication from the sensor node; generating a message that includes a type-length-value (TLV) element based on the statistic, the TLV element including a first portion that indicates a class of the statistic, a second portion that indicates a numerical value for the statistic, and a third portion that indicates a length of the second portion; and communicating the message to a police node in the sensor network.
