What is claimed is: 1. A sensor network for monitoring for the presence of hazardous agents within a geographic area, comprising: one or more RF addressable sensors wherein each RF addressable sensor includes at least one sensor element for detecting the presence of a hazardous agent and a radio frequency identification (RFID) tag element having identification data stored in a memory; one or more wireless telephones coupled to a communications network, wherein the wireless telephones are configured to obtain sensor data and RFID identification data from the one or more RF addressable sensors; and a centralized sensor network processor coupled to a communications network, wherein the centralized sensor network processor receives sensor data and RFID identification data from the one or more wireless telephones. 2. The sensor network of claim 1, wherein at least one of the one or more RF addressable sensors is capable of detecting the presence of a chemical agent. 3. The sensor network of claim 2, wherein at least one of the one or more RF addressable sensors is capable of detecting the presence of a radiological agent. 4. The sensor network of claim 3, wherein at least one of the one or more RF addressable sensors is capable of detecting the presence of a biological agent. 5. The sensor network of claim 1, wherein the one or more wireless telephones are configured to obtain sensor data and RFID tag identification data via an RFID tag interrogation protocol. 6. The sensor network of claim 5, wherein the tag interrogation protocol is a binary tree traversal protocol. 7. The sensor network of claim 1, wherein the centralized sensor network processor includes logic for performing geolocation. 8. A method for monitoring a geographic area for the presence of hazardous agents, the method comprising: (a) distributing a plurality of RF addressable sensors over a geographic area , wherein at least one of the plurality of RF addressable sensors includes at least one sensor element for detecting the presence of a hazardous agent and a radio frequency identification (RFID) tag element having identification data stored in a memory; (b) deploying one or more wireless sensor readers within the geographic area to read the plurality of RF addressable sensors; (c) at each wireless sensor reader, initiating a read of the one or more RF addressable sensors, receiving sensor data and RFID tag identification data from the one or more RF addressable sensors, and communicating the received sensor data and the received RFID tag identification data to a centralized network sensor processor; (d) determining whether the sensor data indicates the presence of a hazardous agent; and (e) if it is determined that the sensor data indicates the presence of a hazardous agent, performing geolocation to identify the location of the RF addressable sensor that communicated the sensor data. 9. The method of claim 8, wherein the read of one or more RF addressable sensors is via an RFID tag interrogation protocol. 10. The method of claim 9, wherein the RFID tag interrogation protocol is a binary tree traversal protocol. 11. A sensor network for the remote monitoring of shipping containers, comprising: one or more packages, wherein each package includes one or more RF addressable sensors, wherein each RF addressable sensor includes at least one sensor element and a radio frequency identification (RFID) tag element having identification data stored in a memory; one or more shipping containers, wherein each shipping container includes at least one of the one or more packages and a wireless sensor reader and wherein the wireless sensor reader is configured to obtain sensor data and RFID tag identification data from any of the one or more RF addressable sensors within the shipping container; at least one transport vessel having a device for receiving sensor data and RFID tag identification data from the one or more wireless sensor readers in the one or more shipping containers; and a centralized network monitoring processor for performing risk management on the received sensor data and tag identification data. 12. The sensor network of claim 11, wherein the centralized network monitoring processor includes logic for performing geolocation. 13. The sensor network of claim 12, wherein each shipping container includes one or more RF addressable sensors. 14. The sensor network of claim 11, further comprising one or more shipping boxes. 15.
