A network includes a supervisory sensor in communication with a wireless network and a non-supervisory sensor in communication with the supervisory sensor, wherein the non-supervisory sensor communicates with the wireless network through the supervisory sensor. The supervisory sensor may be configured to receive downloads from a server communicating through the wireless network and to collect data from the non-supervisory sensor. The supervisory sensor may be configured to transmit the collected data to a server on the wireless network. Moreover, the non-supervisory sensor and the supervisory sensor each have an active state and an inactive state and wherein the supervisory sensor may be in the active state while the non-supervisory sensor is in the inactive state.
