ABSTRACT:
Wireless Vehicular Sensor Node (WVSN) gating radio transmission of a message of the vehicle sensor state of a magnetic sensor by a vehicle-present indication. WVSN may further include ambient sensor generating and transmitting an ambient report. Alternatively, WVSN includes magnetic sensor and ambient sensor used to create messages for radio trasnmission. Method and apparatus for wireless receiving multiple ambient reports from multiple WVSN to create road condition report. The received ambient reports and the road condition report are product of this process. The wireless vehicular sensor network including at least two WVSN sending ambient reports.
