The military services recently have tested, and in some cases fielded, the first set of intelligent nodes, which comprise multiple, similar transducers that enable the node to determine directionality. Because proximity sensors have only a single transducer, they can monitor intruders as they move closer or farther as the signal strength increases and decreases. A vehicle by itself at a certain time or place may not be important; but network-enabled data analysis might reveal a pattern that precedes certain events, so appropriate measures can be taken. Because the intelligent sensor field makes very accurate information available throughout the network, it can be used to make other systems far more efficient.
