System and method for providing self-locating wireless sensors

摘要

A wireless sensor network is disclosed that comprises a plurality of wireless sensors and a wireless sensor base station. The wireless sensor base station sends a request to one of the wireless sensors requesting the location information for the selected wireless sensor. The wireless sensor determines its location using a location information determination method, associates its identity information with the location information, and sends the identity information and the location information to the wireless sensor base station. The wireless sensor continuously sends updated location information to the wireless sensor base station as the wireless sensor moves within the wireless sensor network. The wireless sensor base station displays the identity information and the location information of the wireless sensor on a display unit.

1. A wireless sensor comprising:
a wireless sensor location controller configured to:
determine a location of the wireless sensor,
detect a geographic boundary,detect movement of the wireless sensor, andcontrol a wireless transceiver to wirelessly transmit a signal comprising location information of the wireless sensor in response to (i) detecting the movement of the wireless sensor and (ii) determining that the wireless sensor has passed the geographic boundary, wherein the wireless sensor location controller is further configured to determine a velocity of the wireless sensor in response to detecting the movement of the wireless sensor and control the wireless transceiver to wirelessly transmit the signal in response to determining that the velocity of the wireless sensor is greater than a threshold velocity.
